386 system call fixes:

  * use 64-bit file system calls (Linux, Darwin)
  * use 32-bit [sic] uid/gid calls (Linux)
  * fix sockets on Linux

Darwin/386 works again.

Linux/386 is better but must never have worked;
there are still bugs surrounding the creation of new
threads in the runtime package.
