Small comment: you could just specify compile_targets as "all". I think then you
would not need this.

[Nico, 2015/07/28 15:11:16]

I want the bot to build the default target. (Also, then I end up with "all" and
a bunch of test binaries on the build line, which can be different from building
just "all" – "all" currently means "all targets transitively reachable from
targets listed build/all.gyp", not "all targets in all gyp files transitively
reachable from build/all.gyp")
