gdb builder status (Was: Adding binutils to the GNU Toolchain buildbot on sourceware)

Hi gdb hackers (dropped binutils),

https://builder.sourceware.org now has 6 build only builders.
centos-x86_64, fedora-x86_64, debian-armhf, debian-arm64, fedora-s390x and debian-ppc64.
I like to add a fedora-ppc64le one once that one has enough disk space.

These builders are fairly quick, a few minutes at most. And all except
the fedora-s390x one build fine. They should sent email once a new
failure occurs.

The fedora-s390x failure looks as follows:

There is also one build and check everything builder
https://builder.sourceware.org/buildbot/#/builders/binutils-gdb-fedrawhide-x86_64
I haven't looked at the test results yet, but they are all stored in
the bunsendb.git for later analysis. This builder doesn't sent emails
on bad builds.

One issue with the build-check-everything builder might be the widely
varrying build times which range from 1 to 7 hours.

Cheers,

Mark
