Author: Michael R. Crusoe <crusoe@debian.org>, Julian Gilbey <jdg@debian.org>
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!
