53091ecd20 Attempt to get more applets compile for NOMMU. 
TODO_config_nommu documents what I managed to compile so far
(yay! msh works! cool). inetd, telnetd, httpd still do not compile. TODO
Also make fork(), daemon() produce warnings on compile stage
(in addition to erros on link stage).

67b23e6043 getopt_ulflags -> getopt32. 
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

2f50aa42c5 login: use some ideas from util-linux's login. 
O_NONBLOCKing output on login timeout.
fchmod instead of chmod (latter is racy).
is_my_tty() is not needed anymore after race is fixed
(is_my_tty() was racy too anyway...).

as the old optimization did (actually does slightly better under gcc 4.0), and

d1f8c1c125 From Jan Kiszka: This patch fixes the security labelling of the login terminal 
and process... There still remains some stuff to clean up (the whole
set_current_security_context() appears unnecessary complex to me), but this is
now at least working.
