This matches the -ffunction-sections from bootstrap.pro, which tells the
compiler to create a section for each function. The -gc-sections option
tells the linker to drop what wasn't used (normally, it only drops
entire files).

We'll use nm to get the listing of symbols in the next commit.
The -P option is "portable", which sounds like a good idea. I don't
have access to any of the commercial Unix systems, but I do remember
them printing a different format than GNU binutils's nm.

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.

We depend on Xcode for building Qt itself and user application on Mac OS.
The user may have an Xcode install that is not set up properly, in which
case we would fail compilation in mysterious ways. Instead we try to
detect misconfigured or missing Xcode installs as early as possible.
We try to detect if an Xcode install has not been chosen yet, and
if the user has not accepted the Xcode license agreement. We need to
do these checks both in configure, as early as possible, and in mkspecs
on Mac OS, as we need to error out if the user tries to build an app
with the Qt SDK, but with a broken Xcode install.

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...):

The former applies both on Mac OS X and iOS, but 'macx' is specific to
Mac OS X.
ios.conf and macx.conf now share most of their settings in the common
mac.conf. We set the default QMAKE_MAC_SDK before loading mac.conf, so
that any overrides in the device config will apply afterwards. This
means configure's mkspec parsing will be able to read the QMAKE_MAC_SDK.

This is a step towards making mac a shared scope for both Mac OS X and
iOS, while macx is Mac OS X specific and ios is iOS specific.
We'll then move iOS to not include macx.conf, once we make the change
to not have iOS imply macx.

Building against the local /System can cause build issues when for example
the headers have not been updated to reflect the system version. The system
headers are updated as part of installing the command line tools from within
Xcode, not as part of the system update process, so we might think we are
on 10.8, but the system headers will not reflect that, and we get build
breaks. It's preferable to always build against an SDK, so that we have
a known state for the OS X libraries and headers.
We choose the latests SDK by default, as recommended by Apple.

Instead of setting -isysroot in both arch.test, compile.test, the various
mkspecs, and sdk.prf, we now propgate the chosen SDK as the qmake
variable QMAKE_MAC_SDK, which is then handled exclusivly in sdk.prf.
The QMAKE_MAC_SDK variable, and -sdk argument to configure, is expected
to be of the short-form name, eg macosx or iphoneos, not a full path, as
that's what Xcode also expects. We take care of translating that into
a full path for -isysroot/-syslibroot in sdk.prf, using xcodebuild as
a helper.
