I received a private query about this but will follow up here because
the answer may be useful to others.

The concern: GNU as is still needed for skein_block_asm.s, so is this
not broken? Indeed, GNU as is still needed for exactly one case in the
base system, assembling skein_block_asm.s on amd64. It is still
enabled via BINUTILS_BOOTSTRAP there. Disabling BINUTILS (this commit)
means that GNU as is no longer installed as /usr/bin/as by
installworld, on any arch.

We still need to address skein so that we can completely remove
binutils for FreeBSD 13.0. We have a few possibilities for dealing
with the assmebly implementation, but I currently plan to switch back
to the C implementation for now and follow up with one of those
approaches later.
