Add two patches from upstream, fixing test 39:
* src/extract.c (maybe_recoverable): Treat EMLINK like ELOOP, for
FreeBSD.  Problem reported by Christian Weisgerber in
<http://lists.gnu.org/archive/html/bug-tar/2010-11/msg00080.html>.
Problem reported by Bruno Haible in
<http://lists.gnu.org/archive/html/bug-gnulib/2010-11/msg00306.html>.
* src/extract.c (maybe_recoverable):  Also treat EFTYPE (if defined)
and ENOTSUP like ELOOP.
