[fedora-arm] Assembly scanning tool

[Jon Masters]

Folks,

The attached script is a very simple first stab at an assembly scanning
tool. We can use it to iterate over packages in the distro, looking for
anything that uses inline or dedicated assembly files. Examples too.

I was frankly surprised that bash had such "optimizations" :)

Jon.
