* symbols.c (S_FORCE_RELOC): Return true for indirect functions
	even if !strict.
	* expr.c (operand): Don't convert absolute symbols to constants
	if S_FORCE_RELOC is true.
	(expr): Only reduce subtractions between different symbols if
	S_FORCE_RELOC is false for both of them.
	* write.c (fixup_segment): Don't remove symbols if S_FORCE_RELOC
	is true for them, regardless of their segment.

	* gas/i386/ifunc-2.s, gas/i386/ifunc-2.l: New test.
	* gas/i386/ifunc-3.s, gas/i386/ifunc-3.d: Likeise.
	* gas/i386/i386.exp: Run them.
