     6     $ mkdir build

     7     $ cd build

     8     $ emconfigure ../configure --host=asmjs-unknown-emscripten --disable-assembly --disable-threads --disable-cpuinfo CFLAGS="-O2"

     9     $ emmake make

    10

    33 

    34     $ EMCONFIGURE_JS=1 emconfigure ../configure --disable-mmx
