As a data point, current stable openSUSE still ships Clang 7, so if the
motivation is to leave Clang 5 behind, then 7 could be a good
compromise.

Failing that, using Clang from LODE could work as well, but then please
let's have it documented what you need to put to your autogen.input to
use clang-from-lode. I mean, the clang-from-system case is a matter of:

CC=clang
CXX=clang++
--enable-dbgutil

I assume some more variables are needed in case the clang headers
should not be taken from /usr/include. Or is that not needed?

Thanks,

Miklos
