[Piglit] Running piglit in chroot

[Dylan Baker]

Have you tried just setting your environment variables directly? It's a
pretty common setup to LD_LIBRARY_PATH and LIBGL_DRIVERS_PATH to a local
directory as a means of running piglit against a development branch of
mesa. Unless I'm completely misunderstanding, or there's something I'm
not thinking about, you shouldn't need to patch anything.
