Subject: classes: Add a mechanism, to select components to be able to select
 default compiler

We add clang as an alternative compiler, it sitll uses underlying
binutils and compiler runtime, it will only do the compilation and defer
link, to GNU ld/gold, to compile a component usign clang add

TOOLCHAIN_pn-<recipe-name> = "clang"
DEPENDS_append_pn-<recipe-name> = " clang-cross "

And OE will start using clang to compile <recipe-name>
