Wikipedia says that VAX production ceased in 2005. The last VAX-specific
patch I can see being submitted to gdb-patches is us mentioning support
for VAX floats in the Ada mode (which we removed in 2010). VAX VMS was
removed in 2010 from BFD. There seems to be some regular activity around
VAX on the GCC side, though, but Ultrix itself seems to be no longer be
supported.

So this seems to indicate that we will be able to remove support
for Ultrix.

I suspect that HP-UX will no longer find any takers. AdaCore had to
step-up many many years go to keep those alive. The situation is
different today, and we are stepping down.
