There is a second change to the linking in natty; as announced in [1],
--no-add-needed/--no-copy-dt-needed-entries is passed by default, with
the current gcc in natty, --as-needed is passed as well.  Please see [2]
for implications (runtime failures) and a list of packages which might
be affected.

To revert this change on a per package basis, pass --no-as-needed to the
linker (-Wl,--no-as-needed in LDFLAGS).  To add an explicit dependency
on a library use --no-as-needed -lfoo --as-needed.

Please tag bug reports with `as-needed' if you see runtime failures
caused by this change (mostly unresolvable symbols referenced by plugins
and ldopened objects).
