I did a clean build with same configure options.  It works here.  It
could be some compatibility issue with your LLVM version, but I am not
familiar with the code there.  You might want to file a bug report.

When EGL_DRIVERS_PATH is set, it should be prepended to the search
path.  Did you have the variable set when running the demo?
