I'm checking in the following libffi patch.

This patch from Oliver Kiddle lets us build libffi with the sun studio
compiler.  Obviously this is a non-goal for GCC, but I'm checking it in
from upstream.

	* src/x86/ffitarget.h (ffi_abi): Check for __i386 and __amd64 for
	Sun Studio compiler compatibility.
