Basically, you are trying to use a variable from one recipe in another
recipe. I guess, there is no direct way of doing this. However, you can
echo the ${WORKDIR} of recipe A to a file inside the ${STAGING_DIR} and
then read the contents in recipe B. But, you should make sure that the
recipe B gets executed after recipe A.

Also remember, if you have specified INHERIT = "rm_work" in your
local.conf then the work dir will be removed after the tasks of a
package are completed.

IMHO, depending on files from another package's workdir is a bad idea.
