The whole point is to NOT change the string to begin with, but to use
the unmodified SunOS ld.so and libraries. Look at the
/sys/compat/linux/linux_util.[ch] (or s/linux/svr4/) and see how the
alternate root is handled. I'm sugesting transplanting this into
/sys/compat/sunos (and the other emulations).

Next time I get NetBSD up on a m68k machine I'll try converting sunos if
nobody beets me to it. That'll probably be a while. It doesn't really
look that hard, mostly cut and paste. Perhaps the alternate root code
should be factored out into /sys/compat/compat_root.c or something too.
I'll do the others if you'll send me alphas, pmaxen, etc :-).
