Fix up Linux hints for tcsh, and Configure patch

perl5.003_97[mumble,mumble] contained some hints to work around a csh bug
in some versions of Linux.

Unfortunately, that hint doesn't work for a variety of reasons.  If
anyone's really interested in the anatomy of a failed hint, I can oblige.
Or you can just trust me :-)
