Description: Default to pure python parsing on big endian systems
 The current version fails on big-endian systems as described in
 https://sourceforge.net/p/ruamel-yaml/tickets/360/ and
 https://sourceforge.net/p/ruamel-yaml-clib/tickets/34/
 .
 The current version of this patch completely disables the C extension on
 big-endian systems.
 .
 Thanks to Rebecca N. Palmer for the tip about sys.byteorder!
