Run mojo unit tests on the Android main waterfall.

Run Mojo additional unit tests on the "Android GN" bot:
http://build.chromium.org/p/chromium.linux/builders/Android%20GN
(No CQ yet; need Android GN testing support/devices there...)
Add the necessary target mappings to ninja_to_gn.pyl

Similar tests already run on Linux GN and our chromium.mojo FYI:
http://build.chromium.org/p/chromium.linux/builders/Linux%20GN

Will do, will hold off approval until they're ready.

Hey Dirk, I saw that you landed https://codereview.chromium.org/1153933004/
getting some GN bots ready to run tests, any progress toward Android GN bots
running tests?

Nope, no progress as yet, I've been working on swarming and getting the desktop

moved over. Hopefully progress on Android next week.

Ok, thank you! Please let me know if I can help. Also, the apptest scripts ought
to work on Android even if gtest_tests isn't ready.
