classes/insane: restore printing LIC_FILES_CHKSUM checksum if not specified
OE-Core rev
ec8590aa81e201e28e500935d31cd7266114471f (by me)
unintentionally disabled printing the actual checksum value if no
checksum was specified, i.e.:
LIC_FILES_CHKSUM = "file://COPYING;md5="
Printing the actual checksum in this case is really useful when writing
a new recipe, so put this back in.
