d2af1d71c1 Remove obsolete freebsd-icc mkspecs
The freebsd-icc mkspec was intended to be used with the Intel
compiler, which nowadays is still only available in version
8.1.038 (https://www.freshports.org/lang/icc/) and for i386 only
while the current version is around 17. On FreeBSD the port
was actually never supported by Intel anyway.

b2e9c680e3 qpa: Use LIBS_PRIVATE, not LIBS when linking in font database bits.
LIBS_PRIVATE is more correct (these shouldn't be part of the public API),
and additionally, using LIBS_PRIVATE also ensures these libraries come last
on the link command, which fixes builds using -Wl,--as-needed.

f095ff85c5 qmake: Introduce CE_PLATFORMNAME to fix creation of vcxproj files
While previous SDKs used the form "CE_SDK (CE_ARCH)" in their
configuration/platform names, this is not true fo the Toradex SDK.
Inside Visual Studio the platform is only called "Toradex_CE800"
instead of "Toradex_CE800 (ARMV7)".

In order not to break other SDKs CE_PLATFORMNAME is introduced and
used in the wince80colibri-armv7-msvc2012 mkspec. If the variable
is set qmake uses it as the platform name in its vcproj generator.

34e0e908c8 winrt: Add capabilities as specified by modules
So far no capabilities (but internetClient for Windows 10) were added by
default, which forced developers to always manually edit the
WINRT_MANIFEST.capabilities(_device) property.

This allowed to leave out non-required capabilities and keep the created
manifest clean, examples being microphone for multimedia.

However, this also breaks first user experience as deeper knowledge
about this topic is required. Furthermore this is inconsistent with
other platforms like Android, where all capabilities are set by default
and developers need to edit the manifest manually in any case.
With this change, modules can define the capability set to enable all
features in the module. If developers want to disable some again, they
need to adapt the generated manifest. From our experience this needs to
be done in any case, latest at publishing stage when the store
manipulates the manifest.

523c7e3fd5 build with explicitlib after all
unlike speculated in 2fe363514, this is not a workaround at all: it
causes that libraries' public link interfaces (LIBS) are exported in the
first place. unlike with staticlib, this does not export LIBS_PRIVATE,
so it wouldn't even be a particularly effective workaround for rpath
brokenness anyway.

the problem was pretty well hidden by the qt module system, which at the
level of libraries is pretty redundant with the .prl file handling,
which shows just how stupid the whole "design" is.

unlike before, we now enable explicitlib for all libraries, not just qt
modules - we enable create_prl for all of them as well, after all.

an immediate effect of this change is that it fixes linking on RaspPI:
the qtcore headers make the user code require linking libatomic, so we
must add it to our public link interface.

628d3b7d3a Swap the GCC and Clang versions of supported FreeBSD mkspecs
Modern FreeBSD doesn't come with GCC by default anymore and doesn't even
provide the "gcc" or "g++" falback that OS X does. So there's no point
in keeping the freebsd-clang mkspec in unsupported/ since it's the only
one that works, or keeping the freebsd-g++* ones outside, as they won't
compile.

I'm not removing the GCC mkspecs because you can still install GCC from
the ports tree.

[ChangeLog][FreeBSD] The "freebsd-clang" mkspec is no longer in the
unsupported/ subdir. If you have scripts you use to build Qt, you'll need to
update them to say -platform freebsd-clang or remove the -platform argument.

f24536f8a5 Add tool to namespace Objective-C classes at link time
The feature is enabled by CONFIG += unsupported/objc_namespace,
but can be easily integrated into other build systems such as
CMake or native Xcode by modifying the LD and LDFLAGS equivalent
for each build system.

This is a less resource-intensive alternative to using multiple
Qt builds with different -qtnamespace settings.

Note: The feature is not supported in any way, and should be
used with care.
