    gobject-introspection: Fix inputs when cross-compiling.
    
    * gnu/packages/glib.scm
      (gobject-introspection)[native-inputs]: Add 'bison' and 'flex'
      when cross-compiling.
      (gobject-introspection)[inputs]: Use 'python' instead of 'python-wrapper'
      when cross-compiling.  Remove 'bison', 'flex' when cross-compiling.
