Subject: [PATCH] configure.ac: make pgsql support cross-compile friendly

When cross-compiling pg_config shouldn't be expected to be in PATH
since normally this would point to distribution pgsql rather than cross,
which can be of a totally different architecture.

Change it so we can use ac_cv_prog_PG_CONFIG to point to the real one.
