Upstream-Status: Inappropriate [configuration]

On an Fedora host with glib-config installed pkgconfig-native can get into a
horrible state with recursive calls between pkg-config and glib-config.
The patch adds a configure time option to disable legacy script support in
pkgconfig with the --disable-legacy-scripts option, to maintain compatibility
the default is to leave the scripts enabled.
