fix run-toolchain, qemu-monitor, trace-boot, trace2line, bisect-linux-boot-gem5. Fixes part of #63

I'm sad no one reported qemu-monitor break, that one is kind of important.

count.out arguments broke it as an init program, since the kernel adds trash
parameters to every init.

Is anyone using this repo, I wonder? Keep pushing, keep pushing.
One day it gets good enough, and the whole world will see.

trace2line
