This is the correct way, in my opinion.  The user of libcurl is supposed
to handle environment variable lookup.

This idea has been around for a pretty long time.  I don’t really like
it, but it would solve so many problems where users of libcurl don’t do
env var lookups and fall back to the default, which is not guaranteed to
exist when using Guix on foreign distros or even on Guix System.
