Subject: m4/libtool.m4: FreeBSD elftoolchain strip support

References:
http://savannah.gnu.org/patch/?8675
Message-Id: <20150523-002056.sv85487.59958@savannah.gnu.org>

* m4/libtool.m4 (_LT_CMD_STRIPLIB): Remove the redundant tests for
empty $old_striplib and $striplib.  Move the test for empty $STRIP
variable up. Allow elftoolchain strip (with the same arguments we
used to have with GNU strip) on FreeBSD.
