Bug#862328: Bug scope shrinking

[Kim Gräsman]

Hi all,

I think the most critical problem reported by Sylvain up-thread is
mostly solved, and I can't quite judge the severity of the rest:

This would be nice; I'm currently installing the Clang compiler just
to get at the CMake files required to build it. That seems backwards.
I haven't really gotten my head around the dependency cross-wiring
described by Sylvain, but maybe that needs to be solved first.

This appears to be solved in the packaging as part of the fix for #890514. Yay!

As far as I can tell, this is also solved now --
CLANG_INSTALL_PREFIX=/usr/lib/llvm-7 on my system.

I don't know the status/relevance of this.

Maybe there should be new, distinct bugs for these problems?
