The 'whence' function defined in /etc/profile serves a limited purpose
with Bash as the default shell. Bash already provides
which/type/command as built-ins, which the function simply wraps.
Additionally, zsh has a built-in 'whence' command, which is masked by
the definition in /etc/profile. The function does not work under zsh,
breaking core zsh functionality as a result.
Fixes#18612
