Make switch command with specific perl executable work without symlinks
Make switch command with specific perl executable work without symlinks

We create a new perl version, named custom, and create the link inside it,
and then just use the common case to switch current to this custom
version.

This prevents symlinks in bin/ which would make the use command fail.
