Hmm, that commit didn't fix the issue.
I guess the problem is that this happens in some nested build process
started by guix-environment.sh (that of make-4.1), and not our own build
process?
I'm also puzzled by the cut-off of the shebang string at 77 characters
in the error message, so I looked into it a bit, but nothing strange
here from what I can tell: the ./configure of make-4.1 is called with
SHELL and CONFIG_SHELL set to
/home/taylan/src/guix/build/guix-0.9.1/_build/sub/test-tmp/store/d41iyl2gyk0rwd9z2ddgph9nyg48f3p0-bootstrap-binaries-0/bin/bash
which is exactly 127 characters, but add #! and you have 129. This ends
up being the shebang of config.status, which is why it fails while
trying to call that. Only the error message is broken.
