qjsc.com now has a -n do nothing flag so the makefile can create a
localized binary. See also #267 where we have an exciting new change
aiming to address this particular APE gotcha.
- Compile repl.js & qjscalc.js and include them in qjs.com zip
- Change quickjs-libc.c / js_os_poll to handle Windows console
This last change is needed because poll and select on Windows forbid
non-socket handles and Cosmopolitan Libc hasn't polyfilled that yet.
