    *** error linking uWSGI ***

Disabling LTO seems to fix it. So it looks like a bug in uwsgi, since configuring Python to build --with-lto is a valid option.

$ docker run -it --entrypoint=/bin/bash gcr.io/google-appengine/python:latest
$ virtualenv -p python3.5 /env
$ . /env/bin/activate
(env) $ LDFLAGS=-fno-lto pip install uwsgi
Successfully installed uwsgi-2.0.15
(env) $ /env/bin/uwsgi --python-version
3.5.2

This was fixed quite some time ago. We still don’t use LTO, but that’s a separate issue.
