Assuming 2 items at the end won't work for people using rm_old_work:
http://git.openembedded.org/meta-micro/commit/?id=fcf525654915edb9650f1a6c2852f336366f8b2f
or slightly different version:
http://git.shr-project.org/git/?p=meta-smartphone.git;a=blob;f=meta-shr/classes/rm_old_work.bbclass

And I think more people have different "tmp/" part e.g. default would be
"tmp-eglibc/" (thanks to TCLIBCAPPEND
meta/conf/distro/defaultsetup.conf:TMPDIR .= "${TCLIBCAPPEND}"), but "work" is 
quite common.

meta/conf/bitbake.conf:
WORKDIR = "${TMPDIR}/work/${MULTIMACH_TARGET_SYS}/${PF}"
meta-shr/classes/rm_old_work.bbclass:
WORKDIR = "${TMPDIR}/work/${MULTIMACH_TARGET_SYS}/${PN}/${PF}"
meta-micro/classes/rm_old_work.bbclass:
WORKDIR = "${TMPDIR}/work/${MULTIMACH_TARGET_SYS}/${PN}/${EXTENDPE}${PV}-${PR}"
