rust is especially interesting to me. I currently cannot build my various rust
versions (needed to build MozillaFirefox ESR vs. Release) anymore; details can
be found in
<https://build.opensuse.org/package/show/home:manfred-h:devel:languages:rust:rust-1.46/rust-1.46.0>
and
<https://build.opensuse.org/package/show/home:manfred-h:devel:languages:rust:rust-1.47/rust-1.47.0>.
Both apparently need an "llvm-devel >= 8.0"; I could enable the builtin version
of LLVM as it's done for Leap <= 15.1 or various SLE versions, but as Leap 15.2
has a proper llvm-devel I'd suggest we go down that route to ensure Leap 15.3
has at least the version provided by Leap 15.2 - or even newer. In the interest
to allow building of rust > 1.45, I'd appreciate a solution here. Thx!

That would be really great!
