ELF final_write_processing

Move setting of OSABI to final_write_processing, after symbols are
written.  This allows OSABI to be set based on symbols actually
written to the output rather than assuming input symbols will be
output.

Corrects object files such as the one generated on powerpc64le-linux
by ld-powerpc/pr23927.s which has a local STT_GNU_IFUNC symbol but
prior to this patch the file was marked ELFOSABI_NONE.

	* elf-bfd.h (enum elf_gnu_osabi): Rename from elf_gnu_symbols.
	Remove none, any, all enums.
