rezip_apk_jar?

Done.

this can probably use build/host_jar.gypi (it looks like you would have to make
"jar_path" or just "jar_name" overridable).

I tried this, but it doesn't work. Proguard fails, it appears as if GYP tries to
include rezip.jar in the target jar. Don't know why that would be, GYP is a bit
of a mystery.

'sources' here doesn't do anything.

Removed.
