XCode 4.4 harmful

[Craig Treleaven]

For testing, just use a command line override, aka:

port install mythtv-core.25 configure.compiler=apple-gcc-4.2

I've now tested with XCode 4.4.1, llvm-gcc-4.2 on 10.7.4 and the 
build fails.  This is consistent with XCode 4.3; I could never get 
myth to compile with llvm and had to use apple-gcc-4.2 before I found 
the clang patch.
