You may want to change mach.c in this directory.

Archives MUST have a table of contents. Arch in subdirectory arch
automatically makes one when you change an archive.

Several changes in the assembler were needed to have it generate the 
necessary output.
A contextual diff follows. You can apply them as follows:
patch -d /usr/em/philips/mach/68000/as < READ_ME
