* builds/unix/unix-cc.in (LINK_LIBRARY): Use `-export-symbols'.

This was commented about 10 years ago – I think the reason then to
disable libtool's `-export-symbols' option was to give some badly
programmed applications access to internal FreeType functions.

I believe that we should no longer take care of such programs; the
number of symbols exported should be rather restricted as much as
possible.
