Mesa configure helper script, it will overwrite the /usr/lib/ files on
Ubuntu (run as-is for 64-bit, or use "-32" for 32-bit):

You'll probably want to delete /usr/lib/$dir/*mesa*/*. That's Ubuntu's
invention that will prevent you from using installed libGL and libEGL.
It's all kind of a mess, but I don't know of a better way.
