* Don't try to use auxiliary arguments with statically linked executables.
* Remove 'cannot find interpreter' uprintf, as other exec modules may
succeed in running the binary after all, and then we don't want this message.
* Some linkers produce rw- for the data segment, not rwx.
* Remove a few debugging printfs
2. many termio, ioctl, sigaction fixes
3. better socket type emulation; still ticotsord [the loopback interface I
guess] does not work properly on svr4 4.1.
4. new gettimeofday, fixed utssys..
5. rmdir and mkdir were swapped in syscalls.master
1. always do the stackgap_init()/CHECKALT first in syscalls that need it.
2. svr4_emul_find() uses malloc for the buf, does not use copyoutstr, but
copyout().
Removed makesyscalls.sh; it was really old and we don't need a separate copy.
