Fix OS X configure for Mac OS X

There are some issues with configure.ac which makes the build fail when cross
compiling for Mac OS X:

* The section #### Mac OSX specific stuff ##### comes very late; after several
checks for OS S specific things such as CoreServices and CoreAudio. Obviously,
fundamental things such as mac-version-min and sysroot must be setup before
trying such tests. The entire section should be moved more to the top. 

* The section that checks for CoreServices has two problems: 1) It checks for
FlatCarbon/CoreServices.h. AFAIK, FlatCarbon is a very old concept designed for
compatibility with pre-OS X Mac OS. Since we require OS X 10.5, I see no point
in checking for the FlatCarbon version. 2) There's an hardcoded path to
/System/Library/Frameworks/CoreServices.framework/Headers/CoreServices.h. This
is the wrong way to do it: The path should not be hardcoded, and the
"CoreServices.framework" should not be specified. 

The attached patch should solve both problems. Tested with GCC 4.6.4 targeting
Mac OS X 10.6.
