It does nothing of the kind.  The configure script *checks* what is available,
and uses only the things that are found.  Moreover, use of most external libs
must be explicitly requested, and only then will they be checked for.  Do not
speak in matters of which you do not know.

Sounds like your configure script is horribly broken then.  I'll repeat, there's
a reason patches from this man are usually rejected.
