  Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation Jonas Kulla The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c. I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.

  ================================================================================
  
  Build:
  
      $ emconfigure ./configure --host=asmjs-unknown-emscripten --disable-assembly --disable-threads --enable-cpuinfo=false CFLAGS="-O2"
      $ emmake make
  
  Or with cmake:
  
      $ emconfigure cmake ..
      $ make
  
  To build one of the tests:
  
      $ cd test/
      $ emcc -O2 --js-opts 0 -g4 testdraw2.c -I../include ../build/.libs/libSDL2.a ../build/libSDL2_test.a -o a.html
  
  Uses GLES2 renderer or software
  
  tests: https://dl.dropboxusercontent.com/u/17360362/SDL2-em/index.html
  
  Some other SDL2 libraries can be easily built (assuming SDL2 is installed somewhere):
  
  SDL_mixer (http://www.libsdl.org/projects/SDL_mixer/)
  
      $ EMCONFIGURE_JS=1 emconfigure ../configure
      build as usual...
  
  SDL_gfx (http://cms.ferzkopp.net/index.php/software/13-sdl-gfx):
  
      $ EMCONFIGURE_JS=1 emconfigure ../configure --disable-mmx
      build as usual...
