FreeBSD port (57): ABI tag

[Bruno Haible]

There are not a lot of FreeBSD specific patches to come any more, therefore
here again the patch to define the ELF ABI note format. Neither the FreeBSD
kernel nor binutils have particular support for this ELF section, therefore
I'm free to choose any ABI note contents.


2002-09-04  Bruno Haible  <bruno@clisp.org>

	* abi-tags: Add support for FreeBSD.
	* elf/cache.c (print_entry): Support the GNU/FreeBSD ABI tag.
