Not sure I exactly follow what's happening there.

As we cross-compile wayland
 - the wayland-scanner binary (and thus .pc) should follow --build arch/triplet
 - the wayland libraries the host/target ones.

Are you saying that despite the different arch/triplet everything is
installed in the same place ? I'm not a cross-compilation expert but
the latter doesn't sound right.
There was a related discussion on the wayland mailing list, but I'm
not sure the proposed solution (there) is correct either.

Thanks
Emil
