I stand corrected on those.

pgxs.mk itself requires access to datadir and docdir, so I don't
see how you can maintain that those aren't necessary. The only reason
it doesn't also reference mandir and localedir is that none of our
current contrib modules have any man pages or locale support, but that
hardly seems far-fetched as a requirement for external modules. Also,
pkgincludedir *must* be supported else we cannot set up the -I options
for includedir_server and includedir_internal.

On second look, libexecdir isn't used anywhere, so we might as well just
remove it entirely. But all the others seem necessary to me.
