Duplicate the current machine, which endian is tied to the binary endianness, to one big endian and a little endian machine; updating the machine description. Keep the current default machine for each binary. 'petalogix-s3adsp1800' machine is aliased as: - 'petalogix-s3adsp1800-be' on big-endian binary, - 'petalogix-s3adsp1800-le' on little-endian one.
