OK, can you give me a trace of the output of 'buildman
--list-tool-chains' - I should be able to figure out what is wrong.

You can use the -s flag to see the broken builds, and -se to see
errors also. Is that what you mean?

The output is in ../<branch>/<commit>/<board> but if you want to keep
the binaries, you need -k also.

I haven't tried - can you please point me to one and I'll give it a go.

Yes I remember you talking about this before. One option would be to
add toolchain as a new dimension in the matrix. It might be painful
though. So to be clear, you want to define multiple toolchains for an
arch, and have buildman always build with all of them?
