The strace indicatest that subshell support is either not enabled at all
or that for some reason subshell support has been disabled at runtime...
There are several possible reasons that may lead to subshell support being
disabled at runtime - the most plausible one being MC is not able to
detect what kind of shell you are running. MC supports bash, zsh and tcsh.
It tries to look for the absolute path to the user's shell in the SHELL
environment variable and then in its password database entry.
