Hardcoded parameters cause build to fail on ARM targets

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Build firmware-modkit on an ARM/ARMel target 
2. Build fails on squashfs build

fmk-087.

Also occurs in

It seems that someone decided to 'optimize' that old DD-WRT variant of squashfs 
so that it's compiled with the extended x86 instruction sets of SSE, SSE2, and 
3DNOW. I seriously doubt these instruction sets are even used, or advantageous 
if they are used. The sort of parallel operation on large data sets that would 
make these instruction sets useful just isn't done by squashfs. I have removed 
these switches and pushed the commits. If you see any other issues building to 
ARM, let me know.
