In the glibc headers, there's some (POSIX?) standard macro that points 
at "/gnu/store/.../bin/sh" (I don't recall the name), any reason we 
aren't using that macro?  That would be Guix-independent. I'm not sure 
if a /gnu/store/... prefix is included, but if not, maybe we could try 
overriding it with -D...="/gnu/store/...", or failing that, add a 
post-unpack substitute* replacing [the macro name] -> 
"/gnu/store/.../bin/sh".

Greetings,
Maxime.
