Fix libtool 2.4.2 to correctly detect .def files.

* build-aux/ltmain.sh (sed_uncomment_deffile): New.
(orig_export_symbols): Uncomment def file before testing for EXPORTS.
* m4/libtool.m4: Do the same for the generated code.
--

The old code was not correct in that it only looked at the first line
and puts an EXPORTS keyword in front if missing.  Binutils 2.22
accepted a duplicated EXPORTS keyword but at least 2.23.2 is more
stringent and bails out without this fix.

There is no need to send this upstream.  Upstream's git master has a
lot of changes including a similar fix for this problems.  There are
no signs that a libtool 2.4.3 will be released to fix this problem and
thus we need to stick to our copy of 2.4.2 along with this patch.
