This change adds a 32-bit builder for gccgo and fixes some specific
configuration problems with the docker image/coordinator to speed up builds.
The go builder running on the linux-x86-gccgo image has been modified to run
`make -j16` when building to reduce build times from ~60 minutes to ~10 minutes
and the coordinator has been modified to run the command `make check-go -j16`
to reduce testsuite run times from ~30 minutes to ~10 minutes.

Then make the coordinator and linux environment Makefiles have
an upload target. Amusingly, this actually worked: the Docker
images now tar + compress + upload over HTTP all in a stream,
without even knowing how large the resulting tar.gz will be until
it's done uploading.

Remove subversion & use newer version of the builder which
makes -verbose direct all.bash output to stdout/stderr.

Good checkpoint. Can now do builds by hand.
Next step is coordinator server in front of this, and things
to fire up beefy GCE instances running CoreOS and each build
in its own Docker container. See README for how to do a single
build.
