You need some license information somewhere, legal default is that it is 
illegal to use or to distribute.


In reality this is just bad practice copied from one recipe to another.

For scrypt, see scrypt-0.8.6/LICENSE

python-intervals is even more funny:
LICENSE = "BSD-3-Clause"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/BSD-3-Clause;md5=550794465ba0ec5312d6919e203a55f9"

$ grep ^License: python-intervals-1.5.4/PKG-INFO 
License: LGPL3
