Clean up obfs4/go build on Android
With legacy/trac#28803 (moved) (commit eee5d30a), we added support for Android for the obfs4 build.
In some of the go dependencies, we setup var/compiler
(for example gobsaes
), but not in some others (for example ed25519
).
We should:
- understand why it is needed for some projects and not others
- check if it is really needed for all the projects where we add it
- understand why it is needed for Android, but not for the other platforms
