elfutils: fix for dso link change in recent ld

This patch makes the link to the dependencies of libdw explicit, as recent ld
no longer implicitly links them. See
http://lists.fedoraproject.org/pipermail/devel/2010-March/133601.html as
a similar example of the error message you can encounter without this patch,
and https://fedoraproject.org/wiki/UnderstandingDSOLinkChange and
https://fedoraproject.org/wiki/Features/ChangeInImplicitDSOLinking for more
details.
