lzxpress test

[Matthias Dieter Wallnöfer]

Jelmer,

it would be nice if you could have a look at the lzxpress test 
(../../lib/compression/testsuite.c). It seems not to be big-endian 
compliant - host tridge: 
http://build.samba.org/?function=View+Build;host=tridge;tree=samba_4_0_test;compiler=gcc.

Most probably the "fixed_out" array has to be reordered for big-endian 
platforms in order to pass the test.

Cheers,
Matthias
