for gcc 4.6 which isn't capable of building chromium).

lgtm.

make sure you run this through all of the GN trybots, in particular the android
and chromeos ones; we'll need to make sure the host toolchains are all clang.

Which trybots are those?  I see a bunch of "_ng" bots but i don't see "gn" in
the name of any of them?  Are there specific bots that are not part of the CQ
that you are referring to?

I just triggered the ones that (I think) aren't in the CQ by default. That said,
thinking about it more I suspect they aren't going to catch anything,
so it's probably fine to land this and see what happens.
