ppc_elf_cons and reloc modifiers

[Alan Modra]

I'm not sure why ppc_elf_cons restricted expressions that may have @l
and other modifiers to O_symbol, but it's been that way since rev 1.1
of tc-ppc.c.  This change allows gas to handle code like
	.short x-.@l
	.short 0x12345678@h

	* config/tc-ppc.c (ppc_elf_cons): Allow @l and other reloc
	modifiers generally.
