For now, I'm not entirely sure what "Racket-agnostic" means; the bottom line for my is I think it would be absurdly awful to have to write, e.g. if cross-compiling using `distro-build` with the top-level Makefile:

Example: GUIX_SH=/inputs/bin/sh.

I haven't been following the discussion on the other patches, but didn't I give an example of something independent of the Racket component in use and even independent of Racket itself? See the suggestion of using the already existing _PATH_BSHELL from <paths.h>. It's even not Guix-specific, apparently it's a BSD-ism!

    Greetings,

Maxime.
