Add PSEUDO_NOERROR similar to that used by NetBSD.
Some ports were setting errno in PSEUDO and some were not. Now errno
is set for all in PSEUDO and PSEUDO_NOERROR is provided for the
non-errno case (only used by _exit).
Needs testing on vax and m88k.
XXX - hppa and powerpc still lack a real PSEUDO_NOERROR implementation.
Currently PSEUDO_NOERROR and PSEUDO are the same (so builds don't
break on those platforms).
