[OE-core] Exploring LLVM/Clang for OE

[Muhammad Tauqir Ahmad]

According to the link below [1], it seems some works has been done at
least for llvm+clang bitbake recipes, although I couldn't find any
clang recipes when searching the net. If anyone can point me in the
right direction for finding these recipes, that would be great.
