The buildbot master has been dist-upgraded to Debian Jessie, and now has
GCC  4.9. I have pushed the GDB 8.0.1 upgrades, and they appear to build
fine now.

There was a problem with the phase1 master after the upgrade, the git
poller failed:

This was fixed by removing the work.git directory, after which the
poller recreated it - this time as a bare git repository.

I'll do a dist-upgrade to Stretch in the near future. And thanks again
for giving me access, John.
