[Buildroot] Analysis of build results for 2017-10-30

[Yann E. MORIN <yann.morin.1998@free.fr>]

Thomas, Andr?, All,

Andr?, I'm dragging you into the discussion because we're seeing build
failures that only occur on your autobuilder (at least for now), see
below...

The problem I have is that I can not reproduce the timeout, because it
does work for me here, so I can't even test a fix... :-/

All I have is a prompt about a failure on a certificate...

    $ http_proxy= https_proxy= LD_PRELOAD= BR2_DL_DIR=$(pwd)/yem-dl time make tremor-source </dev/null

So it looks like it is working when stdin is not a tty...

But all tremor failures happen on Andr?'s machine, so maybe there is a
other error condition on his side?
