[AC21.5R21.4] Check for libpq (PostgreSQL) linking against SSL and crypto

APPROVE COMMIT 21.5 RECOMMEND 21.4 It's not a big deal if it doesn't get in to 21.4, nobody's screaming for it, but it might be worth consideration. Probably would need some work for 21.4, let me know if you want it, Vin. This patch adds detection of the case where PostgreSQL links against -lcrypto -lssl. I only know of one case (where PostgreSQL was installed from DarwinPorts on Mac OS X 10.3.9) where it's needed but I don't think it can hurt.
