Changes made in makefile for faster build
I have changed make to $(MAKE) so that we can use multiple threads bypassing the value of the number of threads to be used. Before make emscripten uses single thread while building but after changes to Makefile and passing **make -jN emscripten ** where N is the number of threads to be used.Ex- make -j4 emscripten uses 4 threads instead of single thread.
