Subject: Fix standalone emulator build.

- Allow building with OpenGL ES acceleration disabled, avoiding a
  dependency on stuff outside the QEMU project.
- Allow the standalone configure.sh to provide the include/lib path
  for the OpenGL ES libraries.
- Update the default OpenGL ES include path for standalone builds.
