-Subject: [PATCH] configure.ac: Fix wayland-protocols path
-
-The wayland-protocols directory is used during build: Fix the path
-to point to sysroot specified in recipe.
-
-Normally PKG_CONFIG_SYSROOT_DIR could be used in configure.ac but that
-breaks multilib weston as it would point to multilib sysroot when the
-(allarch) wayland-protocols is actually in the machine sysroot.
