Re: [PATCH] libffi support for CRIS

If we're refering to the patch in
as I think we are, then I'd prefer that gcconfig.h just leaves the
existing definition of CRIS in place, with a comment to that effect,
and tests CRIS later.  The current convention doesn't use
architecture_os macros; it uses separate macros for each, i.e.
CRIS and LINUX in this case.
