    gstreamer1.0-plugins-bad: Define and use WAYLAND_PROTOCOLS_SYSROOT_DIR for output of pkg-config
    
    When configure pokes for wayland-protocols isntallations it ended up
    using the ones from host, which is because it did not account for sysroot
    prefix
    
    Remove MACHINE from variable reference tracking to avoid unnessary rebuilds for different machine
    with same arch

+Subject: [PATCH] Prepend PKG_CONFIG_SYSROOT_DIR to pkg-config output
+
+In cross environment we have to prepend the sysroot to the path found by
+pkgconfig since the path returned from pkgconfig does not have sysroot prefixed
+it ends up using the files from host system. If build host has wayland installed
+the build will succeed but if you dont have wayland-protocols installed on build host then
+it wont find the files on build host
+
+This should work ok with non sysrooted builds too since in those cases PKG_CONFIG_SYSROOT_DIR
+will be empty
+
+Upstream-Status: Pending
