[OE-core] [PATCH] Fix recursive mode -st on BUILDDIR setup

[Alex Franco]

Yes, it was also suggested to check the directories prior to chmod'ing. 
But I'm still not so sure about that, or how extensive the checking 
should be. Perhaps cleaning out sticky bits more extensively could be 
suggested in the documentation.
