Denis Vlasenko 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).
