Attached is a patch to fix the mb linking problems on AIX. As a nice side effect

it reduces the duplicate symbol warnings to linking libpq.so and libecpg.so
(all shlibs that are not postmaster loadable modules).

Please apply to current (only affects AIX).

The _LARGE_FILES problem is unfortunately still open, unless Peter
has fixed it per his recent idea.
