Generally LGTM, but I do have a question (see below).

I guess one of the next steps will be to fix the tests. I'd like to remind you
that test.py and test-wrapper-gypbuild.py are deprecated and will be deleted
soon. Instead, you'll have to update tools/run-tests.py,
tools/testrunner/local/statusfile.py, and most of the test/$SUITE/$SUITE.status
files (never mind their .status2 counterparts, those are auto-generated).

File build/android.gypi (right):

Are you sure this block of changes is necessary? We already have the same
settings in common.gypi, that should be enough to have them apply to Android
build targets too.

Fixed per your review, and rebased on r13717.

Note that mips build is currently busted, pending
