remove_2.9_and_export.sh

to get rid of this, remove llvm-2.9 from ubuntu like this:

sudo apt-get remove llvm-2.9 llvm-2.9-dev llvm-2.9-runtime

and then export the right version for emconfigure like this:

[~/bin/emscripten (master)]$ export LLVM_ADD_VERSION="3.0"
[~/bin/emscripten (master)]$ echo $LLVM_ADD_VERSION
3.0
[~/bin/emscripten (master)]$ ./emconfigure
