oops!, I was a bit confused, lzo is better in speed not with compression 
ratio!. So I think should keep gzip be default. Maybe switch to lzma by 
default when Linux support it. (squashfs-tools already support it but is 
disabled by default)

Maybe can be a good idea to build squashfs-tools also with xz support so 
will be prepared when lzma support become ready on Linux.
