Wouldn't some of the other sparc ports need this?
(Note, please sanity check this, to me specs are a twisty maze of
little passages, all alike.)

Tested via cross-compiling cc1 to sparc64-unknown-linux-gnu and
sparc64-unknown-netbsd and compiling random C programs with -m32 -m64
to see that the error message is sent.

Ok to install?

	* sparc/linux64.h (CC1_SPEC): Error for -m32 and -m64.
	* sparc/netbsd-elf.h (CC1_SPEC32, CC1_SPEC64): Likewise.
