# 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.
