+Subject: [PATCH] Fix all-variables sysroot prefix problem
+
+According to the pkg-config specifications (or rather documentation)
+only the -L/-I directory entries should be sysroot-prefixed.
+
+We also need to prefix the mapdir/sdkdir variables since they're used by
+xorg and expected that way.
+
+Also allow prefixing for includedir and libdir since in some silly cases
+the directories may be requested barebones via pkg-config
+--variable=includedir libfool for example.
