Hi Mark

This won't work well when package is populated from sstate is there a way
for it to work seamlessly across sstate it might be useful

the sstate-cache runs, and the associated pkgdata is dumped to the disk the
S and B for the current directory is written.  But when sstate-cache is
used, there is no extracted source (or build) components so those
directories remain unresolved.
