Delightful!

Can we just change this to a positive set of platforms?

['chromeos==1 or OS=="win" or OS=="linux" or OS=="mac"' ..

(in fact the same condition as the flag immediately above.) Then later we can
remove the non-chromeos ones.

That becomes tricky since chromecast \implies{} OS="linux". I've updated
all.gyp, gn_migration.gyp, and src/BUILD.gn to carry more of the conditions that
the targets previously had so that this isn't needed. Once it's chromeos-only we
will need to do a simplification pass, but there were TODOs for that already.

Acknowledged.
