package/python/106-optional-expat.patch

   1 Add an option to disable expat
   2
   3 This patch replaces the existing --with-system-expat option with a
   4 --with-expat={system,builtin,none} option, which allows to tell Python
   5 whether we want to use the system expat (already installed), the expat
   6 builtin the Python sources, or no expat at all (which disables the
   7 installation of XML modules).
