Ah, now I see the example in the manual: "Specifying the LIC_FILES_CHKSUM Variable".  In my case I have the license as a separate file in my files/ directory for the recipe. So in my case I now set:

LIC_FILES_CHECKSUM = "file://${WORKDIR}/license.txt;md5=blahblah"
SRC_URI = "file://${BP}.tar.gz \
    file://license.txt \
    "

Now the do_license step is finding the license in the WORKDIR and I no longer have any warnings about the license.

Thanks!
