[patch RFA libffi SH] Fix configure error for sh4-unknown-linux-gnu

[Kaz Kojima]

Hi,

The attached patch is to fix libffi build failure for
sh4-unknown-linux-gnu.  Without it, configure fails with:

configure: error: "libffi has not been ported to sh4-unknown-linux-gnu."

on that target.  OK for trunk?

Regards,
	kaz
