OK, have the problems with the native compiler worked out.  Configuration
problem on the host computer.

Now, it's building the native compiler using the new compiler with no problem.

This is planned to be a compiler for a "bare metal" system.  Is there a way I
can disable the library for the cross compiler from being generated with
support for 'files', which I don't have on a bare metal machine?

The compiler fails with:

which makes perfect sense, since there is no file system.

Any suggestions (other than 'forget about it')?
