commit 5af94260490c8083c5b297e7990abd9bd61a9cbd
Author: Alexandru Gagniuc <mr.nuke.me at gmail.com>

cbfstool: Eliminate global variable "arch"
Now that unused functions have been removed, the global "arch" is only
used in very few places. We can pack "arch" in the "param" structure
and pass it down to where it is actually used.
