I'm not sure you need to introduce this change.
The case already exists (stat, fstat, old_select, lstat, ...) and the
entry that was used is:
MIPS_SYS(sys_ni_syscall , 0)
perhaps you can do the same ?
I think the do_syscall() will return -ENOSYS as the TARGET_NR_XXX is not
defined for o32 in linux-user/mips/syscall_nr.h.
Thanks,
Laurent
