I think we're getting off-track here.  The PostgreSQL project is
always willing to accept new buildfarm machines.  In the absence of
buildfarm machines, we try not to go around randomly breaking things
that were previously working.  But the current situation is that we
have good reason to suspect that a couple of very old platforms are
subtly broken.  In that situation, I think removing the
thought-to-be-broken-code is the only sensible approach.

Now, we're not crossing any sort of Rubicon here.  If buildfarm
machines show up - or, hell, if ONE person with access to the hardware
OR a simulator shows up and can compile test EVEN ONCE that a patch to
re-add support compiles and that the regression tests pass - then we
can add support back in two shakes of a lamb's tail.  In the meantime,
leaving broken code in our tree is not a service to anyone.
