newLisp compile to webassembly (newlisp-js)

[iNPRwANG]

Use this makefile can compile newLisp to newlisp-js in emscripten v1.37 by enable webassembly support.

Notice of the  "-s WASM=1" option let the emscripten generate webassembly, and should use the " -s EXTRA_EXPORTED_RUNTIME_METHODS='["ccall", "cwrap"]' " for function exporting (the "ccall" and "cwrap" not export by default in emscripten version above 1.3)



The approximate performance about webassembly enabled newlisp-js is 5% faster than asm.js version (tested in Firefox 58.0.1), and the total file size is less than the asm.js version about 20%.

# makefile for newLISP v. 10.5.x and after with UTF8 support for the Emscripten SDK
#
# With Emscripten version v1.22.0 all execption handling related problems
# known have been solved. (November 2014)
#
# see also: https://github.com/kripken/emscripten/wiki
#
# Uses custom random() and srandom() in nl-filesys.c
#
# Does not implement the newLISP functions:
# semaphore, net-packet, net-service, fork, spawn, sync, abort
#
# Will not do file and network I/O functions in the sandboxed JavaScript
# environment
#
# Generates newlisp-js-lib.js and newlisp-js-lib.html.
# The html file can be discarded use newlisp-js/newlisp-js.html instead
#
# this makefile has been tested on a MAC OSX 10.9/10 platforms
