[patch libffi SH] Fix failures for libffi.call/err_bad_abi.c

[Kaz Kojima]

Hi,

I've applied the attached patch which fixes failures for
libffi.call/err_bad_abi.c on SH.  It's similar to the changes
done already on other targets.  Tested on sh-linux.

Regards,
	kaz

	* src/sh/ffi.c (ffi_prep_closure_loc): Don't ASSERT ABI test,
	just return FFI_BAD_ABI when things are wrong.
	* src/sh64/ffi.c (ffi_prep_closure_loc): Ditto.
