commit 695884b0bddeb312eb90bfd3ea05c85b92f0ee0d Author: Alexandru Gagniuc mr.nuke.me@gmail.com Date: Sun Feb 2 22:37:28 2014 -0600
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.
