i?86-elf and x86_64-elf targets default to
-fasynchronous-unwind-tables, like most other x86 targets, and so
since they build crtend.o they need to build it with
-fno-asynchronous-unwind-tables, like other targets.  This patch
accordingly makes them use i386/t-crtstuff.

I'm not set up for full testing of these targets with FSF sources, but
did a sanity check on this patch by building cc1 for i686-elf, and in
a 4.6-based tree it fixes "ld: error in crtend.o(.eh_frame); no
.eh_frame_hdr table will be created.".  OK to commit?

	* config.gcc (i[34567]86-*-elf*, x86_64-*-elf*): Use
	i386/t-crtstuff.
