I personally did. I understand that what comes out is nothing official,
but it helps to at least look at non-related build issues.

I don't have strong opinion on whether we should switch for Linaro
builds, but would like to see stronger motivation than "it might be
slightly faster" ;-). There're in particular bunch of ideas how to make
android-build quicker, but going for them w/o actual benchmarking might
be waste of time or lead to adverse effects...
