--- Comment #3 from Joe Konno <joe.konno at linux.intel.com> ---
Arnaud's feedback was really good, thanks so much:

"""
I believe your patch is not right, as pq says the sysroot normally contains
the code compiled for the target, which might not be compatible with the
host.

I think the proper way to do this is to compile wayland for the host
separately, and use ${CHOST}-pkg-config instead of pkg-config to get the
wayland-scanner path. In practice you would call
x86_64-linux-gnu-pkg-config --variable=wayland_scanner. The
x86_64-linux-gnu-pkg-config utility will look for pkgconfig files in the
host sysroot, instead of the target sysroot, allowing this use case to work.

Unfortunately not many packages do this correctly...
"""

I'll go ahead and close this bug as invalid. Thanks again for the reviews and
feedback!
