This is a good argument.  Since I really do not expect any response from
upstream I think its not worth another upload to revert my change (and
if I'm wrong and a fix is provided in Git I can do so anyway).  However,
I'll stop disabling LTO for other packages and will follow your advise.

Thanks a lot
