The toolchain build scripts are currently defining the tooltool
manifest they use on their own. We move the definitions to the
taskcluster job definitions to normalize on everything using that.
While here, since the tooltool call from the cctools build scripts was
verbose, make the one in tooltool-download.sh verbose. It will benefit
the other things using tooltool-download.sh, making debugging easier
when one needs to look at the tooltool download logs...
Also use the same cctools as cross-mac builds of Firefox.
Do dummy changes to the corresponding build scripts so that the builds
are force triggered (toolchain builds are not triggered automatically
when the tooltool manifest they use changes yet).
The cctools-port build scripts were pulling and building the master branch
of the cctools-port repo, which means they'd build whatever was there
when they get triggered. I think this was copied from my build-cctools
script which did the same thing, so it's my fault in the end! This patch
pins a revision in the script so we'll build the same thing until we
explicitly update.
I also fixed the scripts to use git instead of tc-vcs, since tc-vcs prints
misleading error messages, and nothing else uses that anymore.
Finally, I removed the build-cctools script, since all the builds are using
cctools-port now so it doesn't serve any useful purpose.
