License files must have their own checksum.
The typical usage could be
LICENSE = "GPLv2"
LIC_FILES_CHKSUM = "file://${COREBASE}/meta/files/common-licenses/GPL-2.0;md5=801f80980d171dd6425610833a22dbe6"
or
LICENSE = "GPLv2"
LIC_FILES_CHKSUM ?= "file://${COMMON_LICENSE_DIR}/GPL-2.0;md5=801f80980d171dd6425610833a22dbe6"
LIC_FILES_CHKSUM is mandatory in every recipe, unless LICENSE is set to CLOSED.
LICENSE = "CLOSED" # No need for LIC_FILES_CHKSUM valiable in this case
