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.

Clang does not recognize the compiler flag 'no-arc-abi' anymore.
This causes a warning, which will fail the build. Not sure
what the flag does, as I cannot find any documentation for it, even
after grep-ing through the sources (both clang-600.0.57 and
clang-503.0.38)

The Xcode and SDK settings are expensive to resolve, as we're using
system() calls to resolve them. We now try to detect the presence of
a .qmake.cache file (and inform the user that creating one would be
a good idea), and use the file to cache the various settings after
resolving them.
The Xcode logic had to be moved form xcode.conf as part of the mkspec,
into default_pre/post.prf, so that we could cache() the resolved values.

Replace all tabs with proper space characters and consistently align
the '=' characters. The default alignment for the '=' of 25 characters
has been left as is to get a minimal diff. Lines with the '=' further
to the right and those belonging to 'proper code (TM)' have not been
touched.

come in handy again...):

Qt uses a lot of minor C++11 extensions such as long long, commas at the
end of enumerator lists, and extra ';' outside of a functions, and not all
of these can be silenced, so we build without warnings for C++11 extensions,
since we plan to enable C++11 at some point anyways.

We need to figure out where to draw the line when it comes to warning
about unknown compiler (Clang), Xcode, or SDK versions, but for now
building with Xcode 4.6 should not be an issue. We'll have to revisit
this and test with the full set of compiler/Xcode/SDKs we support
before the final release.
