Are you sure that is not just a limitation of the qemu transparent emulation?

I examined the test failures in proot-static and it's clear that qemu will have
some trouble finding out what one wants to happen:

>#include <stdlib.h> /* exit(3), */

Now, qemu transparent emulation still picks up, but then the missing
argv[0] will be a problem.

And indeed,

$ guix environment -s armhf-linux proot-static
[...]
[env]$ ./test-25069c12
