Currently we don't reset/override the destdir variable, so we end up inheriting whatever the caller's environment has for it. While it may work, it's not particularly consistent (be that within the script or other tools) nor is it obvious. While in here, ensure we handle the variable with test -z/-n instead of varying other constructs. Signed-off-by: Emil Velikov <emil.l.velikov@gmail.com>
