Making stretch-security build logs public

[Emilio Pozuelo Monfort]

Hi,

I was wondering if we could make old stretch-security build logs public. I
suppose there's nothing private there anymore (no more embargoed updates in
stretch) and it can help in debugging issues with updates (e.g. I just uploaded
a new thunderbird version there and I've noticed that the previous versions
failed to build on arm{hf,64} and I wanted to refresh my memory on why.

Thanks,
Emilio
