7e0fbf9c26 tar: conditionally don't wait for vforked child to exec, as it always
works right on Linux, and anyway mayresult only on less-than-clear error
message only, it will not cause tar to misbehave.

7510384107 do not do utime() on links, it acts on link targets, and we don't want that.
rename link_name to link_target, less confusing this way.

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).

3376298b59 Stop tracking buffer size - it is a constant.
Stop ignoring write errors.
Fix bugs in this line:
rc->buffer_size = read(rc->fd, RC_BUFFER, rc->buffer_size);
(a) should use safe_read()
(b) just ONE short read (e.g. 4 bytes) will make ALL future reads short!
