No. The cross-* part is an overlay on CBUILD (ie the machine building the
software; for a native build this is the same as CHOST in make.conf.)

Well that should happen too: it's a trivial patch, which again has
already been discussed in #-embedded. Either vapier gets on and does
it now he's back, or someone else will, for an arch they care about. I
can't see him caring if it's correct; and after all the mask on the
"overlay" itself (which is on CBUILD, remember) is only possible due
to the separation inherent in the crossdev design.

Nowadays people like to call that "belt'n'braces" or something. When I
learnt to code it was called "common-sense." Discussing it wouldn't
even arise: it goes without saying.
