Landing trivial change.
Change doesn't break build_fuzzers or build_image or coverage.

Change doesn't break build_fuzzers or build_image or coverage.

I'm not sure if helper.py uses this. This is a dependency needed for GCB scripts (e.g. https://github.com/google/oss-fuzz/blob/master/infra/gcb/build_project.py).

Since you've already landed this, we can manually kick off some project build (I've just launched zlib) and see if it goes through.

Yeah, both regular build and coverage job finished successfully, thanks for the upgrade!
