GDB uses the shell to launch the debugged program. That is probably where
‘/bin/sh’ is entering the picture here. I don’t know whether that has any
relation to your foreign distro’s libc being used.
The output of `help run` in GDB mentions that the shell is specified by the
‘$SHELL’ environment variable. Perhaps you have that set?
One way to see if this is the problem is to use the GDB command
`set startup-with-shell off` to make it launch the debugged program without
the shell.

Another alternative worth trying is the ‘--container’ option to ‘guix
environment’, to completely isolate GDB from the foreign distro. You might
want to add the coreutils package to the ‘--ad-hoc’ list so that you can
get amenities such as an ls command. :-)
