I've been doing a similar thing to avoid copying unneeded stuff from a
"non-pure" toolchain (STLinux toolchain), but by using a blacklist
file and rsync's --exclude-from option.

Would it be interesting to anyone else (besides me) to have this
generic approach? It'd be a simple addition to this patch.
