package/libgtk2/Config.in
Allow DirectFB to turn on LIBGTK2 support without X being enabled.
Disable autoselection of cups.  May not be wanted (Can cause crosscompilation issues).

package/libgtk2/libgtk2.mk
Remove unnessary redefine of PKG_CONFIG_*
Pass $(DISABLE_LARGEFILE) to configure (supports large file or not)
Move 'cups' to X extra dependencies instead of general.
