This is expected. In 1.39, --layout=system does not use any decoration of the
names, so that to match it's intended purpose -- system integrators. You
are trying to build both ST and MT variants and put both to 'stage' directory,
which results in name clash.

I can introduce new --layout=tagged that would encode threading and
variant into the name. What do you think?
