libpq is not linked against readline either way.

We can do that.

This is not portable to other non-ELF systems.

The compiler driver (gcc) should provide -lc if necessary. Manually
specifying -lc can cause problems at other places. I just tried building
the ODBC driver on FreeBSD and didn't see a problem, so maybe it's
something with NetBSD's GCC installation?
