dcfeeef91e Remove the -no-rtti option from configure
It only applied to Windows (not MSVC, like the help said) and the build
was broken with this option. So remove it, as we clearly never test
this.

[ChangeLog][Windows] The -no-rtti configure option was removed, as Qt
5.8 fails to build under that condition. To disable RTTI on user code,
add to your .pro file: CONFIG += rtti_off.

52d64fca66 revert to building qmake with qconfig.cpp
turns out that just appending builtin-qt.conf isn't a good idea:
executable-editing tools (objcopy, prelink, etc.) will happily drop the
"attachment".

a safe method would be adding a proper section to the executable, but
there doesn't appear to be an objcopy equivalent in msvc, and using
entirely different methods of embedding the file with different
toolchains seems like a rather bad idea.

so instead go back to the old method of building qmake with a generated
qconfig.cpp. of course, as said file is now created by qmake itself, we
have to compile qlibraryinfo.cpp a second time, and link a second qmake
executable.

this makes it consistent with the determination of the default
include/library paths. this makes sense, as it's possible to switch the
sdk/toolchain after building qt (within reason).

a side effect of this change is that for compilers which emulate other
compilers, both the real and the emulated version are now made
available.

ab0cc3055d move all target spec handling to qmake-based configure system
we pull this feat off by booting configure with a dummy spec. the proper
spec gets loaded subsequently.

note that it was necessary to move the cache loading after processing
the early checks (from which the spec handling is triggered). this is
just fine, as the cache is needed only by tests, which are forbidden at
this stage by definition.

169a40d511 move generation of qconfig.cpp (and qt.conf) to qmake-based configure
this moves us another step towards the "outer" configure doing just
minimal bootstrapping of qmake.

a challenge here was that so far, qmake itself needed qconfig.cpp. this
was replaced by usage of a qt.conf file instead of compiled-in values.
however, to make the executable still self-contained, that qt.conf is
embedded into it (by simple appending of a fixed signature and the text
file).

the qmake with the embedded qt.conf is not used for the qt build itself,
which instead relies on the qt.conf in bin/ as before. however, due to
the missing built-in values, this file now needs to contain more
information than before. but except for a minimal version that is needed
to start up qmake/configure at all, that file is now also generated with
qmake. as some of the newly set up properties are subsequently used by
configure itself, qmake gains a (deliberately undocumented) function to
reload the qt.conf after it's fully populated.

unlike the old implementations, this one doesn't emit redundant qt.conf
entries which match the hard-coded fallbacks. omitting them leads to
leaner files which are more comprehensible.

42196f4061 nuke configure -host-option
in its current form, it was introduced only in 5.7, mostly as a side
effect of -external-hostbindir (which is now handled differently).
it only ever worked for the macOS and MinGW specs, as a side effect of
them supporting -sdk and -device-option (for good reasons), and was
supported only by the unix configure. it's not believed to be really
useful and complicates matters somewhat, so get rid of it again.

should it ever become actually relevant, it can be re-introduced
properly, probably along with a -host-sdk option for macOS.

60e5a1c8ef Modularize the new configure system (infrastructure part)
This change implements the required infrastructure to modularize the new
configuration system.

This requires a hierarchy of configuration files, both for handling
multiple repositories and for individual modules inside the same
repository.

When configuring, they all need to get loaded first, as command line
processing needs to know about all possible command line options.

When the command line has been processed, the individual configuration
files need to get processed one after the other and independently from
each other.

Configure is now automatically invoked when building the a project
tree's "root" project; this works with both modular and top-level builds
of Qt (the latter with an according change in the super repo). As an
immediate consequence, the -skip option moves to the super repo with a
different implementation, as configuration is now done after the repo
list is determined. The option belongs there anyway.

This commit also adds an optional testDir entry to the json file. Like
this, we can still have all configure tests in qtbase/config.tests and
the configuration file in, e.g., corelib can reference those.

The files section can now be left out as long as a 'module' entry is
present, specifying the module name. The names of the files to generate
can then be deduced from that name. We still need to be able to specify
names directly for the global configuration files.

qtConfig() now also queries features which are module-specific. As it is
sometimes necessary to query the configuration of modules which should
not be actually linked (and cannot in the case of subdirs projects), the
new variable QT_FOR_CONFIG which allows specifying configuration-only
dependencies is introduced.

73331eebf8 Enable precompiled headers on iOS, tvOS, watchOS
The actual blocker for precompiled headers is not the iOS/tvOS/watchOS
platforms, but the way qmake handled multiple-architecture builds on
Apple platforms.

This patch allows multi-arch builds to be performed while using
precompiled headers.

Since df91ef3d6c55692a0236f67b6c6b134a3bf84098 (April 2009), Clang has
had support for PCH files in the driver, which allows to use the
-include flag to automatically translate to -include-pch. We can then
take advantage of the fact that the -include option is allowed to not
be separate from its argument, which lets us take advantage of -Xarch to
specify a per-architecture precompiled header file.

This is done through some magic in the qmake Makefile generator which
"multiplexes" the PCH creation rule across multiple architectures and
replaces a series of tokens with the proper precompiled header paths
and architecture flags at usage point.

this removes some code duplication between tests and project files (in
case of conditionals), and ensures that the projects always actually use
the libraries configure has found.

d5dc46d319 employ QMAKE_USE: LIBS += $$QMAKE_LIBS_FOO
this migrates the cases where the build system already made (some) use
of variables (possibly) set by configure.

97b856b788 Use the qmake based configuration system also on Windows
Adapt configure.exe to use qmake to do most of the work of configuring
Qt. This unifies a large part of our configuration system between Unix
and Windows. configure.exe is now still doing the license check,
creating qconfig.cpp, building qmake, and not much more.

On the way, re-implement the still missing Windows-specific tests with
the new system.

The opengles2 vs. opengl-desktop conditions got a bit convoluted, as
Unix prefers desktop GL, while Windows GLES2 (via ANGLE). Superficially,
there is a circular dependency, but the platform scopes are supposed to
break it.

fd3e12e7a6 replace mechanism to override variables from the mkspecs
it is sometimes desirable to override values from the mkspec without
modifying (or wrapping) the spec itself. linux distributors do this on a
regular basis.

so far, we'd pick up CFLAGS, etc. from the environment, in a somewhat
autoconf-like fashion. however, over time, this approach proved
problematic: the concept doesn't mix particularly well with mkspecs to
start with, is unexpected (and therefore causes frustration), and
doesn't mix well with cross-building (at least the way it was realized).
ironically, it was implemented this way (quite a while ago) upon my
explicit request ...

the new mechanism uses explicit variable manipulations on the configure
command line, just like qmake itself understands. as it happens, this is
again quite similar to autoconf-generated configure scripts. however,
this time around we don't pretend to be actually autoconf-like, so we
also don't try to map any variable names (some of which have different
semantics anyway).

this commit also eliminates the last use of the QMakeVar() function,
so delete it and the underlying infrastructure.
