Historically this option has been passed to the script. This is
supposedly because at the beginning the script was placed
outside of the ruby source tree. Decades passed since the merge

Just ignore the passed value here.

Old script says this option is a "separator for vpath". I am
confident we no longer need this option.

This option used to override VM option that is defined in
vm_opts.h. Now it is officially unsupported because vm_opts.h to
remain mismatched with this option must break things. Just edit
vm_opts.h directly.

We use const whenever possible now so this option is ignored.
The author believes that C compilers can constant-fold.
