The following changes were once useful, for building ECOFF-format
NetBSD kernels that one could simply drop into a bootable Ultrix
root partition and boot.  They may not be so useful anymore;
it depends how faithful an ultrix binary emulation NetBSD should
provide.

I'm posting them again because they're not yet in NetBSD-Current,
the format of the syscall.master file appears to have changed, and
this seems like a sensible time to merge them into the NetBSD-current
tree.
