Yes (as mentioned on IRC), this is as intended and documented in
deb-src-control(5). The rationale is that a :native build dependency on
M-A:foreign package is non-sensical, one of the markings is wrong
because if the interface is arch-indep then requesting the native
should not be required.

So the assumtion here is that this is a problem in linux. Thus
reassigning.
