The above is harder than necessary. You run bitbake, find something
isn't set, set it, run bitbake, find something else isn't set, set it,
run bitbake, etc.

"Simple" from the user perspective is that it just works and you don't
have to set anything.

IMO, in 95% of cases a user wants the default virtual provider. The only
problem is that at present bitbake has no way of working out what that
is...

If this worked properly there should be no more nasty issues with
external-toolchain bothering people and angstroms distro.conf should
become a lot simpler...
