In 'ci/run-docker.sh' we run 'docker run' with a bunch of '--env ...'
options to make some important environment variables available
inside the container.  At this point in this script all those
variables are set to the expected values, but ...

... but here, for some reason, those environment variables are not set
anymore.  This is bad, because this CI job then builds Git
sequentially, runs the tests sequentially, runs the tests with 'make'
instead of 'prove', and runs the tests without '-V -x'.  IOW, it's
slow, it produces a lot of useless output, it doesn't report all the
failures, and doesn't tell us anything about the failures.

The recommended way to build Git is without autoconf and configure.
You can set the PYTHON_PATH and USE_LIBPCRE Makefile knobs in
MAKEFLAGS in 'ci/lib.sh', but to be able to access MAKEFLAGS in the
container you'll need to build this patch series on top of:
