I tracked down this error.

It's a bootstrap error.  I built this compiler with a slightly older one
that wrote IL foreign language information into .module_dep files.  But
after the new compiler was installed it couldn't read the .module_dep files
that had been installed for its standard library modules, as support for IL
has been removed.  After failing to read .module_dep it looked for a .m file
in the current directory to attempt to rebuild the dependencies.  The
solution is that I should bootstrap with a slightly newer ROTD.

We should be aware of this in case it affects anyone else.
