Is there an easy way to do a T-push (builds on all platforms, tests on
one platform only) with |mach try fuzzy|?

I usually do T-pushes using try syntax, by Trychooser seems to be out
of date when it comes to building a T-push syntax for Android, so I'm
at a loss as to how to do a T-push for Android right now.
