Richard,

I already explained my use-case with external toolchains - those usually come 
with specific set of libc-headers. And when those don't match the list from 
OE-Core, it causes problems, trying to support some resemblance of multilib. 
I believe that got disabled completely now for external-toolchains anyway...
