gmp-5.1.0-RC2 in connexion with GCC builds

[Denis Excoffier]

Hello,

Please consider some more dialogue with GCC people: at least in GCC-4.7.2 (the last stable version)
and in the last GCC-4.8 snapshot (in both, see Makefile.in at top level), gmp is configured
with --host=none-..., and this seems incompatible with your new configure.in:

AC_MSG_ERROR([the \"none\" host is obsolete, use --disable-assembly])


When i modify gcc-4.7.2/Makefile.in to use --host=${host_alias} etc. i also fall into
the now expected ".../libgmp.a(mod_34lsub1.o), in section __TEXT,__const reloc 0: etc." message
(i use darwin12.2.0).

Regards,

Denis Excoffier.
