Subject: Build with LTO


LTO has been explicitely disabled because of build issue with the
optimization. It seems however that these issues are fixed now and
Fedora guidelines ask to use default build options unless absolutely
necessary. Reenable LTO.

Also clean the specfile a little: no need for all these commented out
lines related to git sources.

Resolves: RHEL-46715
