[PATCH 2/4] build: AC_PACKAGE_WANT_GDBM, fall back to compat if libgdbm detection fails

[jeffm@suse.com]

From: Jeff Mahoney <jeffm@suse.com>

We currently check if libgdbm_compat contains the required symbols
even if libgdbm does.  Let's fall back only when necessary (which
is pretty much always anyway).
