Re: Results of a multi-build (not good)

I've been asked if I could release the multi-build script.  It's attached 
below.

Note that it only builds the debuggers, it doesn't run any tests on them.  
To do that I would need to build and install about 36 sets of complete 
tool chains, which I just don't have space for.  Further, most of them 
wouldn't be much use without either a simulator or a real piece of 
hardware to test them on.

You will need to tweak the variables at the top of the script to your 
local configuration.

R.
