As the new project ships a maintained, up-to-date version, the need for
bundling bug-fixed versions of ARPACK has disappeared and the projects
have started to unbundle their own flavors of ARPACK.

On the Fedora side, we'll just drop any patches currently present in
the ARPACK package (which have become part of the new upstream release)
and rebuild.

If no-one disagrees to the procedure, I'll push the new version to
rawhide as soon as upstream adds the missing libtool script in the

Furthermore, since the library is only used by freefem++, I might as
well push the version to other branches, too, so that removing the
bundles can be done in them as well.
