I'm not sure this works when cross compiling.  What you really want to
do is look for wayland-scanner on the build machine rather than the
target.  With these changes we will try and run wayland-scanner for the
target (assuming it has been built).

It doesn't look like there is currently any way of using the m4 macros
shipped with pkg-config to run the right one.

For now I think it is better to just look in PATH, although getting the
feature into the pkg-config m4 scripts and then using it would be good
in future.
