Toolchain WG helper programs

[Michael Hope]

We've got a few little helper programs that are used in the Toolchain
WG to help things run smoothly.  I've done a short write up on them
here:

Ulrich, this is the build system I mentioned on the call.
Scott/James/Mounir, it's not great, but this gives you an idea of the
tools I'd like to hand over.
