fc8dca9dac heuristic to stop pulling .6 in from .a

let the dead code/data eliminator throw
away the parts that weren't useful.

unless given -d flag.

the resulting binary doesn't *use* any dynamic libraries,
it just has a reference to the dynamic linker and an
empty list of needed symbols and libraries.

this is enough to make 6.out binaries that can be run
under dtrace / dtruss.

if stack is in low memory and frame size is huge, test could wrap around!
fix by omitting test altogether if we know frame is big.

d28acc42ec first cut at multithreading. works on Linux. 
* kick off new os procs (machs) as needed
* add sys·sleep for testing
* add Lock, Rendez
* properly lock mal, sys·newproc, scheduler
* linux syscall arg #4 is in R10, not CX
* chans are not multithread-safe yet
* multithreading disabled by default;
  set $gomaxprocs=2 (or 1000) to turn it on

This should build on OS X but may not.
Rob and I will fix soon after submitting.

9aad9fef76 make 6a, 6c, 6g, 6l, libmach_amd64 build on 64-bit gcc. 
these guys really really want long to be 32-bits,
so ,s/long/int32/ (and then manual fixup).
still passes all tests.

(i started out looking for just those longs that
needed to be int32 instead, and it was just too hard
to track them down one by one.)

the longs were rare enough that i don't think
it will cause integration problems.
