[gas] Handle m68k-uclinux like m68k-elf in EXTERN_FORCE_RELOC

[Bernardo Innocenti]

2004-01-16  Bernardo Innocenti  <bernie@develer.com>

	* config/tc-m68k.h (EXTERN_FORCE_RELOC): Handle m68k-uclinux specially,
	like m68k-elf.
	* config/tc-m68k.c (RELAXABLE_SYMBOL): Use EXTERN_FORCE_RELOC instead
	of hard-coded test for TARGET_OS=elf.
