Purpose of commit: bugfix

Commit summary:
---------------

Only the libdb ndbm compat mode works, all the other don't work.
So check for libdb at first.

2006-01-27  Thorsten Kukuk  <kukuk@thkukuk.de>

        * configure.in: Prefer libdb over libndbm, fix check for
        libcrack and remove not needed BACKUP_LIBS.
