Profiling support is currently missing on aarch64, but it should be included in glibc-2.18. For now, can we just disable it for aarch64?

Attached is a patch from Mark Salter that disables profiling in star. Also attached is the spec file I used for testing the build. 
It adds the new patch and adds aarch64 to the list of Linux platforms (for rules).
