Makefile: fix find -printf issue on FreeBSD

Apparently the use of -printf was causing the error: "printf: missing format character" with FreeBSD 11.1-RELEASE. Change the helpers lib count to rely on -print0 and tr, which should be more portable, but still be undisturbed by unusual paths. Thanks to Curtis Dunham for reporting the problem and proposing an alternate solution. Signed-off-by: Rob Browning <[email protected]> Tested-by: Rob Browning <[email protected]>
