[OE-core] [PATCH] gnome-doc-utils: Prepend PKG_CONFIG_SYSROOT_DIR to the path returned from PKG_CONFIG

[Khem Raj]

If we build say gnome based image on a build system which does not have
gnome e.g. kubuntu then packages like gedit do not build since it uses
gnome files from host system which are non existent on kubuntu

+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. Now usually people have gnome installed
+so the build succeeds but if you dont have gnome installed on build host then
+it wont find the files on host system and packages using gnome-doc-utils wont
+compile.
+
+This should work ok with non sysrooted builds too since in those cases PKG_CONFIG_SYSROOT_DIR
+will be empty
