Hm. This doesn't seem like a bright way to be forcing an rpath.
The problem is that you have no idea what search order will result
when this is combined with any -R we ourselves might have included
or will later include into our LDFLAGS. As an example of possible
breakage, suppose you are trying to install PG into /opt/postgres
and there is already an old version of PG in /usr/local. You've
got about a fifty-fifty chance whether the produced binaries will
search /opt/postgres/lib before or after /usr/local/lib --- and
the second way is wrong, because they'd find the old version of
libpq.so.
Ugly as it sounds, I think you'd be better off setting the entire
Postgres rpath by hand by specifying LDFLAGS to configure.
The other thing that's a bit strange here is the reference to
libpthread --- does libxml2 really depend on that? I'd definitely
advise against linking libpthread into the backend if you can
avoid it.
