With the above patch it now fails to compile on powerpc. Error is:

compiler/nativeGen/X86/Regs.hs:407:10:
    The type signature for `freeRegBase' lacks an accompanying binding

Currently testing a patch to fix it.

Fixes this so it compiles on PowerPC. Tested on x86 and x86-64 as well.

Fixed by removing the freeRegBase function in non-x86 builds.
