[test-suite] disable darwin -force_cpusubtype_ALL option for ppc64-elf-linux

[Will Schmidt]

We occasionally see gcc throw some unrecognized command line option
errors when working on the test suite on ppc64-elf-linux.

>  gcc: error: unrecognized command line option ‘-force_cpusubtype_ALL’
>  make[4]: [Output/test1.llc] Error 1 (ignored)

The option is specified in Makefile.programs ; and per the comments
there, it is a darwin specific flag.   Thus, should be disabled for
Linux targets.

OK to commit?  

Thanks,
