I'm curious to try Clang with OE too, but the last time I checked it
still is not possible to build a valid kernel using Clang alone.
Therefore I would assume if I wanted to use Clang it could only be for
building user-space things and I'd still need a cross-gcc compiler for
the kernel. Is that the current plan?

If we were to do it, I'd arrange to have enough of the patches from the
Clang team in the yocto kernel, to provide a valid building kernel. i.e.
it is possible now, just not with a stock kernel.

But it's all theoretical at the moment, since we aren't actually close
to trying anything yet :)
