it's unclear where to look for the error when the message talks about
'g++' when '${CROSS_COMPILE}g++' would have been expected. help it by
saying whether it was supposed to be the host or target compiler.
this also centralizes the error emissions in a function.

With 4183475080, Qt fails to build if
qmake is unable to detect the compiler's default include and
library search paths. Clang on non-Darwin systems was missing working
code for the detection.
Unlike GCC, Clang on its own does not print the library search paths
when called with the -v option.
On Darwin, the -Wl,-v option will reach ld64, which will print those paths.
However, neither GNU ld nor gold will print anything useful with just
-v. GNU ld has a --verbose option that does print some search paths, but
those are not the ones used when ld is invoked (via collect2) by GCC or
Clang, so it can't be used.
To make Clang print its library search paths one can use
-print-search-dirs, which however doesn't print include search paths. So
amend the existing code in order to make a second call to clang on
non-Darwin systems. This second call is used for library path detection,
and fixes the build on non-Darwin (tested on Linux).

... and rename those determined by toolchain.prf to QMAKE_* (this was
already the case for the newly introduced msvc and icc variables).
this restores the ability for user projects to query the toolchain qt
itself was built with, which is necessary for compatibility checks.
in fact, we may do such validation in toolchain.prf itself at a later
point.

The configure-time detection (cxx11default) isn't enough if the compiler
can be changed. This is especially necessary if Qt is compiled with a
compiler that defaults to >= C++11 (e.g., GCC 6) and then the user
selects a compiler another compiler (e.g., Clang) via -spec option. In
that case, we'd miss adding the -std=c++11 or -std=gnu++11 option to the
command-line, causing the compilation to fail.
As a nice side-effect, even moc without moc_predefs.h will now get the
__cplusplus setting.

note that in principle this leaves room for a race condition, as the
first project to determine the host config is not going to be the
top-level one.
in qtbase and qtdeclarative, this is naturally serialized via the common
bootstrapped libraries (bootstrap resp. qmldevtools). activeqt, qt3d,
qtscxml, and qtwayland all build only one bootstrapped tool each.
qtwebengine makes a fake host build to create files for gyp/gn; the
convert_dict tool is declared a host tool, but isn't actually built when
x-building anyway, and even if, it's serialized on the former. qttools
needs explicit serialization, though. no other host builds exist within
qt as of now.

in cross-builds, toolchain.prf was loaded before CROSS_COMPILE was set
up, leading to caching of possibly nonsensical values.
this change also necessitated that msvc-version.conf is loaded only when
toolchain.prf is, which is best done by loading the former from within
the latter. that seems quite appropriate in the first place.

the code got factored out to an own toolchain.prf file, which is
load()ed from default_pre.prf, so no change at first.
however, on mac, we shadow toolchain.prf, and make it load() sdk.prf
first.
a side effect, it has become harder to disable the use of an sdk
altogether: putting CONFIG-=sdk into a project file or the qmake
command line has no effect now. instead, it's possible to put it into
.qmake.{conf,cache}.
to make it simpler again, it's conceivable to finally add qmake -pre,
which would allow setting variables before default_pre.prf is executed.
take 2: there was nothing wrong with the original patch, but in 5.8,
CONFIG+=simulator_and_device moved from qconfig.pri to various prf files
that would do it according to the simulator_and_device configure
feature, which would be way too late for the "pulled ahead" sdk.prf
loading. as simulator_and_device is now gone entirely, it is safe to
re-apply this patch (mostly) as-is.
