commit 2d4a359fbb92e96f95031256c2896fe7354b3621 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.
