If a recipe, which uses the fsl-eula-unpack bbclass, defines the
variable LIC_FILES_CHKSUM like
LIC_FILES_CHKSUM = "[...]"
(not using "+=") the content of ${FSL_EULA_FILE}, which is added in
fsl-eula-unpack, is overwritten. So the EULA isn't deployed to the
${LICENSE_DIRECTORY}.
Using 'LIC_FILES_CHKSUM_append' should work in any cases.
