George Koehler 02fb480217 Commit a preview of osx386 and osxppc as new platforms.
These produce Mach-o executables for Mac OS X on Intel or PowerPC
processors.  Our code generator for PowerPC (mach/powerpc) still has
bugs.  Some examples seem to run, but startrek crashes.  Our code
generator for Intel (mach/i386) is better.

There is a problem with job control.  If you run paranoia or startrek,
then suspend the job (^Z) and resume it ('fg' in bash), then read(2)
might fail with EINTR.
