A trailing slash or consecutive slashes anywhere in TMPDIR cause BitBake variable expansion to embed those redundant slashes into derived variables such as STAGING_DIR and WORKDIR. The sstate machinery in sstate_add() normalises its directory arguments via os.path.normpath(), so manifest entries always contain clean paths. Functions in staging.bbclass that read the same variables directly via d.getVar() without normalising then fail to match manifest entries, silently staging files to wrong locations and causing do_populate_sysroot to abort.
Although POSIX permits paths with redundant slashes, they break the string-matching assumptions embedded in the staging machinery, so treat any TMPDIR that differs from its normalised form as an error.
