Looking at http://autobuild.buildroot.net/?reason=traceroute% gives
some interesting details:

 - Until May 2018, the problem was happening with external toolchains.

 - Then, there's a big gap, with no traceroute failures at all

 - Since September 11, 2018, the problem started happening again, but
   this time around, only with internal toolchains

I looked at the commits on September 10/11, but couldn't spot anything
that looks obviously related. It is also not clear why the problem
disappeared on May 2018. However, back then, it was happening only on
Matt Weber build machine. Since September, with the internal
toolchains, it is happening on apparently all autobuilder machines.

Weird.
