[PATCH]: Compile libgcc and pass -relax to linker (HC11/HC12)

Hi!

I've committed this patch to compile libgcc HC11/HC12 with -mrelax and
benefit from linker relaxation.  We must pass -relax to the linker when -mrelax
is specified.

	* config/m68hc11/m68hc11.h (LINK_SPEC): Support -mrelax.
	* config/m68hc11/t-m68hc11-gas (LIBGCC2_DEBUG_CFLAGS): Can use -g now.
	(LIBGCC2_CFLAGS): Compile with -mrelax.
