Instead of lumping both Objective-C (.m) and Objective-C++ (.mm) sources
into the same pile, passing them on to the same compiler as for C++ (CXX),
with the C++ flags (CXXFLAGS), we follow Apple's lead and treat them as
variants of the C and C++ languages separately, so that Objective-C
sources are built with CC and with CFLAGS, and Objective-C++ sources
with CXX, and CXXFLAGS.
This lets us remove a lot of duplicated flags and definitions from the
QMAKE_OBJECTIVE_CFLAGS variable, which in 99% of the cases just matched
the C++ equivalent. The remaining Objective-C/C++ flags are added to
CFLAGS/CXXFLAGS, as the compiler will just ignore them when running in
C/C++ mode. This matches Xcode, which also doesn't have a separate build
setting for Objective-C/C++ flags.
The Makefile qmake generator has been rewritten to support Objective-C/C++
fully, by not assuming that we're just iterating over the C and C++
extensions when dealing with compilation rules, precompiled headers, etc.
There's some duplicated logic in this code, as inherent by qmake's already
duplicated code paths, but this can be cleaned up when C++11 support is
mandatory and we can use lambda functions.

If no_generated_target_info is not set, VERSION is set, and
there is no .rc file that belongs to the project, qmake creates a
.rc file that contains information about the target's version
and copyright, for example. This resource handling is also
supported by WinRT and we can add this information to the target.
On Windows Phone, winresrc.h (which is needed for resource
handling) is not available though. When trying to add a .rc file
to a project in Visual Studio, it also complains about winres.h
not being available. Instead of hacking around the issue, we
just should not support this behavior on Windows Phone.

This linker script is only enabled for systems with GCC or GCC-like
compilers, though technically it should work on the BSDs too (will
enable after testing). For regular modules, this declares one ELF
version "Qt_5" and places all QtCore symbols inside, then it declares
unused ELF versions "Qt_5.x" for each older minor release. For modules
declared "internal_module", all symbols are placed in version
Qt_5_PRIVATE_API.
The big advantage of an ELF version is that, when we do Qt 6, both
versions of QtCore could be loaded in memory without conflicts and all
symbols would be resolved to the correct library. No module can talk to
both at the same time, but this avoids mistakes of loading them
indirectly by plugins.
The extra Qt_5.x versions will be used in the next commit.
