meta-clang has options when it comes to C++ runtime, default is to use
gnu runtime, other options are llvm runtime and android runtime. This
patch helps when a distro is using llvm runtime for C/C++ runtime. It
informs the rust build system about right C++ runtime to configure for
when such a setting is used.

I think it is a little bit over complicated, couldn't it just be:
if "llvm" in (d.getVar('RUNTIME', True) or ""):
config.set("llvm", "use-libcxx", e(True))
I'd much rather we did some kind of indirection via a variable too
since I'm not sure OE-Core knows anything about RUNTIME, or that
RUNTIME is a particularly good choice of name for the core.
Cheers,
Richard

OK. I have pushed this into yoe/mut on contrib and testing it. I think
it will work ok.

Thats fine, I am not vested in name as much, although it might be used in
other places too by now. but if we were to have a convention in
OE-core which is different
thats one time bullet to bite.
I think we have few bugs open in bugzilla
https://bugzilla.yoctoproject.org/show_bug.cgi?id=11528
https://bugzilla.yoctoproject.org/show_bug.cgi?id=9417
which attempt to bring various portions of toolchain options into
core. We have been
postponing it for quite a while. if we want to consider it something
for next LTS, this
would be right time to start.
