[PATCH] wayland: Add target sysroot scanner m4 macro

[Richard Purdie <richard.purdie@linuxfoundation.org>]

With the new aclocals process, accesses to the macros is a lot stricter and
the native macros are not used. We need to ensure the modified macros are used
in target builds to get the correct scanner functionality. Inserting the
native macro into the target is the correct thing to do in this case.

This resolves build failures in libva.
