It is slowing all the staging projects/etc. Which we rebuild daily.
If we take look only on stock SLE rebuild counter we rebuild everything quite
significantly
http://ostrich.suse.de/build-times/project/SUSE:SLE-15:GA/index.html thus if we
spent 3 mins on avg doing something it is unfortunate.

Maybe we should disable dwz on staging projects to speed up at least those
common rebuilds.

FWIW there are even bigger slowdowns in lieu of brp checks and rpmlint but the
plan is to look at them somehow too.
