This needs the (now relatively common) `libtool` patch, but allows us to
sidestep a bunch of issues that relate to linking static libraries into
position-independent executables.
Having this option enabled made `libuuid` link to `libintl` only when
the `gettext` port was installed. This made the `taskwarrior` port
fail to build when `gettext` was installed prior to `libuuid`.
We may need entries with spaces in makeopts, installopts, and
configopts, and at that point we should also convert depends and
auth_opts to avoid confusion.
