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
