I'm a little reluctant to remove "obsolete" from the description --
maybe "deprecated" instead?

is compatible with output emulation set by "-m emulation".
This is OK. Thanks!
hmm, this breaks any released gcc on aarch64-linux-gnu and
arm-linux-gnueabi*
$ gcc -fuse-ld=gold foo.c

What do ld.bfd -V and ld.gold -V report? They should support the
same set of emulations.
powerpc-linux-gnu as well:
