PowerPC .gnu.attributes

This patch extends Tag_GNU_Power_ABI_FP to cover long double ABIs,
makes the assembler warn about undefined tag values, and removes
similar warnings from the linker.  I think it is better to not
warn in the linker about undefined tag values as future extensions to
the tags then won't result in likely bogus warnings.  This is
consistent with the fact that an older linker won't warn on an
entirely new tag.

include/
	* elf/ppc.h (Tag_GNU_Power_ABI_FP): Comment.
bfd/
	* elf-bfd.h (_bfd_elf_ppc_merge_fp_attributes): Declare.
	* elf32-ppc.c (_bfd_elf_ppc_merge_fp_attributes): New function.
	(ppc_elf_merge_obj_attributes): Use it.  Don't copy first file
	attributes, merge them.  Don't warn about undefined tag bits,
	or copy unknown values to output.
	* elf64-ppc.c (ppc64_elf_merge_private_bfd_data): Call
	_bfd_elf_ppc_merge_fp_attributes.
binutils/
	* readelf.c (display_power_gnu_attribute): Catch truncated section
	for all powerpc attributes.  Display long double ABI.  Don't
	capitalize words, except for names.  Show known bits of tag values
	when some unknown bits are present.  Whitespace fixes.
gas/
	* config/tc-ppc.c (ppc_elf_gnu_attribute): New function.
	(md_pseudo_table <ELF>): Handle "gnu_attribute".
