Okay, it's in.  In addition to fixing the problems previously discussed,
I found it necessary to change the osabi registration (in mips-linux-tdep.c)
from:

  gdbarch_register_osabi (bfd_arch_mips, 0, GDB_OSABI_LINUX,
                          mips_linux_init_abi);

to:

  for (arch_info = bfd_lookup_arch (bfd_arch_mips, 0);
       arch_info != NULL;
       arch_info = arch_info->next)
    {
      gdbarch_register_osabi (bfd_arch_mips, arch_info->mach, GDB_OSABI_LINUX,
                              mips_linux_init_abi);
    }

I'm not entirely happy with this change, but I see no way around it
due to the recent changes to osabi.c.  (I'm open to suggestions for
better ways to do it...)
