Subject: [PATCH] Build every ECPG library with -DFRONTEND.

Each of the libraries incorporates src/port files, which often check
FRONTEND.  Build systems disagreed on whether to build libpgtypes this
way.  Only libecpg incorporates files that rely on it today.  Back-patch
to 9.0 (all supported versions) to forestall surprises.
