Perl builds emit warnigs, cmake builds fail.

Every Perl package build spits a warning like this:

Note that is is for ages resolved in recent Mock versions.
If you want to set it for the 1.3.4 version which Fedora Koji is using, then this should
be enough:

config_opts['environment']['LANG'] = os.environ.setdefault('LANG',
'C.UTF-8')

Right. That is tracked in #6967. If mock is upgraded, this issue should go away too.

This is not an issue in Copr as Copr use Mock 1.4.x, which already set the LANG variable
to C.UTF-8

So, all builders (except armv7) are moved to new mock, but it did not change the LANG to
C.UTF-8. :( 

So I also tried adding 'config_opts['environment']['LANG'] =
os.environ.setdefault('LANG', 'C.UTF-8')'

But I see still:

I don't know if thats koji or mock isn't configured quite right. Further
investigation will be required...

``
`config_opts['environment']['LANG'] =
os.environ.setdefault('LANG', 'C.UTF-8')` only has an effect if the
host's environment has `$LANG` not set.  I assume you need to replace that with
`config_opts['environment']['LANG'] = 'C.UTF-8'`.
