I think there’s an impurity leading the build system to use lib64/
instead of lib/.  Compare with what we get with “real” Guix:

--8<---------------cut here---------------start------------->8---
$ ls $(guix build -e '(@@ (gnu packages commencement) libstdc++)')
include/  lib/  share/
--8<---------------cut here---------------end--------------->8---

Heh.

Could it be that the above libstdc++ was built before you had enabled
chroot builds?  Are you sure the chroot doesn’t contain /bin or anything
like that?

(Are you sure you don’t want to use guix-daemon?  :-))
