PATCH: Compatibility with "am"/"ams"

[H . J . Lu]

gcc 2.96 from Red Hat uses "am"/"ams" for SHF_MERGE. But now binutils
no longer accepts them. That means you cannot use the current binutils
with gcc 2.96. That can lead to many unnecessary problems. I can deal
with it myself. I think we should provide a safe compatible binutils.

	* config/obj-elf.c (obj_elf_parse_section_letters): Accept "am"
	and "ams" for compatibility.
