Data corruption on big endian #12

I'm working on getting Squash working on big endian (POWER8), and zling is one of the codecs which currently fails there:

[fedora@squash-be build]$ ./zling_demo e < CMakeLists.txt | ./zling_demo d > t && sha1sum CMakeLists.txt t

If it would help, I can provide temporary access to a VM for debugging and testing. Just e-mail me or drop by #squash on freenode.
