But most -- in fact all except perhaps yourself and a few of the OE core
team don't build with different LIBCs in the same TMPDIR.  So all that
your patch does for the overwhelming number of users of OE is add
additional directory levels to an already complicated directory
structure, and provides them with absolutely no benefit whatsoever.

At the very least, you really should provide a means to selectively
enable this -- although I still don't see why it makes sense to support
multiple LIBCs in the same TMPDIR.
