BTW, if such a change isn't made (though I'd be very curious to know
why -- is using a non-cross pkg-config _ever_ useful when
cross-compiling?), I think there would still need to be a way for
configure scripts to detect this situation (a non-cross pkg-config
chosen while cross-compiling).

Currently I just have my configure script completely disable use of
pkg-config when cross-compiling (by setting PKG_CONFIG=""), but
obviously this is undesirable if a cross-version of pkg-config was
actually found...



Occam's razor split hairs so well, I bought the whole argument!
