Good point.  It would be better to leave that out, because simpler.
I included it because it was in the default search path for gcc-4.6.

Testing with gcc-4.2 reveals that you're right, though I'm not sure I
understand why.  After dealing with libgcc_s.so, using

	gcc-4.2 -B/usr/lib/$arch

to compile a C file that uses <ffi.h> works fine.
