scripts/gdb: refactor rules for symlink creation
gdb-scripts is not a real object, but (ab)used like a phony target. Rewrite the code in a more Kbuild-ish way. Add symlinks to extra-y and use if_changed. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
