### Please describe the problem.

There were a few changes introduced since then to Makefile (I will not guess which one broke it) which resulted in git within git-annex-standalone of neurodebian to be unable to clone from https://:


[[!format sh """
$> /usr/lib/git-annex.linux/git clone https://github.com/afni/afni_ci_test_data.git                            
Cloning into 'afni_ci_test_data'...
fatal: unable to find remote helper for 'https'

so may be that is related.

Unfortunately in datalad we had no test testing cloning over https, so I added such integration test in https://github.com/datalad/datalad/pull/3867 to at least detect such regressions in the future before hitting the userland
