I'll look into this one tonight. Been meaning to work through a few of
these cross PR's

That's documented I beleive

Hmmm...probably no reason it can't use the one that's spit out from tools/gcc3

I beleive this is documented also (that you need a C++ compiler). If it's
not fully documented about HOST_CXX file a PR for that.

Yes

I need to look here but I beleive it needs HOST_CC there, not the cross one.

That's a gnu'ism
