I'm not against such change, it would be an update to SLE15-SP1 rust
(we don't want to split sources for this).  Given rust isn't happy with
llvm9 the >= 6.0 check is "bogus" anyways.  There's only a group of maintainers
though, CCing.

So if we "fix" rust then pulling 'llvm' from Factory into Leap works?  Can you
stage that (change rust in Leap) to try?
