Hi Piotr,

thanks for the bug report.

Yes, errors like this are due to the missing support for -flto in
Libtool.

I started a patch series for fixing Libtool:
<http://thread.gmane.org/gmane.comp.gnu.libtool.general/10794/focus=10808>
<http://thread.gmane.org/gmane.comp.gnu.libtool.patches/9767>
but so far, only one of the four patches got merged.  Some still
needs further work, some still need review.

For example, my fellow maintainers could review these:
<http://thread.gmane.org/gmane.comp.gnu.libtool.general/10794/focus=9769>
<http://article.gmane.org/gmane.comp.gnu.libtool.general/10810>

Cheers,
Ralf
