* Ignore broken multidir directories

When a multidir directory is not really a directory or a valid symlink to one,

we want to skip it instead of exploding.

This patch fixes that by doing a simple sanity check while processing the

configured multidirs.

Thanks to Ralph Giles <giles@ghostscript.com> for the report and the patch.
