Yup.

The thing is that if we remove support for some port from binutils,
then we need to remove it from gdb too, because gdb uses bfd, etc.,
as you know, otherwise, it's possible that an --enable-targets=all
build breaks.

Or seen from the other angle, if we don't want to remove it
from gdb, then we need to keep it in bfd too, etc.  (Not that
I expect that)

So for a.out in particular, I was implying that while gdb still includes
some support for a.out, it's already scheduled for deletion, so that
shouldn't be a blocker.  I should have been more explicit,
sorry about that.

To be clear, I'm all for removal of old unused ports.

Thanks,
