Fix for coroutine/win32/Context.obj

2018-11-28T01:04:39+00:00

* coroutine/win32/Context.asm: old ml version 9 needs CPU
  directive before `.model` directive.

* win32/Makefile.sub: specify object directories to separate Win32
  and Win64 targets.  Win32 rule was overridden by Win64 rule and
  just ignored.

Change Makefile rule for assembly to use .S rather than .s

2018-11-24T11:35:29+00:00

It is more conventional to use compiler to pre-process and
assemble the `.S` file rather than forcing Makefile to use `.s`.
