Link libpq after libpgfeutils to satisfy Windows linker.

Some of the non-MSVC Windows buildfarm members seem to need this to avoid
getting "undefined symbol" errors on libpgfeutils' references to libpq.
I could understand that if libpq were a static library, but surely it is
not?  Oh well, at least the extra reference is no more harmful than it is
for libpgcommon or libpgport.
