	# FIXME: change made 24 Jul 2006 by the OE folks changes the "strip"
	# behavior to create an extra file named .debug/<filename> containing
	# the stripped symbols.  These files are supposed to be packaged
	# separately by the standard bb routines, but for some reason this
	# does not alway occur.  This extremely ugly step is to remove the
	# debug cruft from the rootfs if any are left in the obvious locations.
	# Once someone figures out why and what the right way is to fix this,
	# this code should be removed.
