I was trying to use gcov on Postgres and ran into a problem where some contrib
modules were missing the key libcov symbols and failed to load. Korry very
helpfully tracked down the missing bit: the broken modules were ones built
using "gcc -shared" according to the rule in Makefile.linux which doesn't have
-lcov.
Actually better than adding -lcov, I think this rule really ought to have
CFLAGS in it in case there are other CFLAGS that are necessary at link time.
