Yeah, this all LGTM, and gets my:

I'm wary of doing that, if only because it establishes a pattern. It's
fine for wayland-protocols itself, but when doing sysroot builds,
includedir/libdir/etc already get prefixed by the compiler/linker. So
I wouldn't want anyone to look at wayland-protocols and blindly copy
the prepend to prefix. Containing it to just variables we know will be
used and queried directly seems more safe.
