Subject: [PATCH] Allow passing custom RANLIB to Makefile.direct

Issue #666 (bdwgc).

By using "?=" operator we only set the RANLIB variable in case it does
not already have a value.

* Makefile.direct (RANLIB): Assign value using operator "?=" instead
of "=" one; place comment before the definition; mention Cosmo in
comment.
