should this go into some android-specific section?

Files that have platform names in their paths aren't compiled on other
platforms, so it's not necessary - you can find cases where this is done, and
cases where it isn't, some I'm not sure what the preferred style is.

For what it's worth, net/net.gypi does not do that.

sgtm. I thought it only applied to name suffix, nice to know.
