Agreed, getting a supporting buildfarm animal set up would be an
important step if we wanted to accept such a patch.

Ah!  So maybe a more convenient way forward is to reject any patch for
adding support for this in autoconf, and tell Frank to use our Meson
build instead.  (Not available until 16, but of course so would be the
case with whatever patches he came up with at this point.)

Our autoconf build system is on the way out anyway: even if it's not to
be removed in the near future, ISTM the writing is now in the stone that
it'll eventually be gone.  So adding a new feature is likely a waste of
time.
