    Fix compiling Mac OS 10.5 Universal App Bundle
    
    Need to be able to specify minimum Mac OS X version outside of the
    Makefile to avoid conflicting CFLAGS.
    Moved -mmacosx-version-min LDFLAGS into the Makefile.
    Moved -arch x86_64 from OPTIMIZEVM to CFLAGS to fix linker errors
    (previously make-macosx-ub.sh passed it to CFLAGS manually).
