Sorry.. it was submitted before I was finished...

I have this in my local tree.  I recall Ian and I discussing that since
Go and GCJ both need libffi, the logic should be smarter.  But this works.

I submitted patches to libffi for m68k and mips.  I recall Go built and worked
on at least i386, sparc, mips, powerpc, and arm.   So libffi is OK to enable. 
If libffi doesn't support a particular architecture, then Go and GCJ are not
available on that architecture.
