OK, so that would explain why there is no /usr/bin/as on our ref-aarch64
boxes in the cluster.

So does it come with assembler, is it GNU-compatible?  (I was told it
does: s/${AS} ${ASFLAGS}/${CC} -Wa,${ASFLAGS:ts,}/)  If yes, why there
is no wrapper installed as /usr/bin/as?

Or it cannot be used as a drop-in replacement and users that want to
call as(1) directly should install `devel/binutils' port?  Thanks,
