Well, I am not convinced, this would make any sense.

There is only one reason for this flag anyway: 
* "rmdir -p /etc/olsrd/foo" removes every directory down to the 
  first non-empty one (i.e. "/etc")
* rmdir will return "1", as "/etc" could not be removed.
* gmake will stop as a command returned non-zero.

One possibility to fix this on GNU is "--ignore-fail-on-non-empty",
which lets rmdir return zero.

Other ways to solve this would be:
* Clean: Do not use "rmdir -p", make "uninstall" remove just the
  (directly) targeted directories -> this won't remove
  "/usr/local/lib", just because it is empty after uninstalling
* Quick fix: Which has more or less the same behaviour as it is 
  now: Just ignore the return value of rmdir.
  I just saw that one may prefix a gmake Recipe with "-" to 
  ignore the return value. This is probably nicer than "|| true"

Anyway, you opt for removing the "-p/kill-them-all" switch alltogether, 
then there ain't no need for RMDIR_OPTIONS any more.
If you use the "-" prefix, this will make the only possible 
RMDIR_OPTION redundant, too.
