State-Changed-Why:
    The proposed fix will not work as the problem is more
    gross than that.  The problem is that thread_builddir
    is independently settable yet mirrors a location known
    to be set.  The correct fix IMHO is to remove
    thread_builddir (map all such uses to target_builddir)
    and add dependancies to the related stamp file (i.e. do
    not depend on directories).

>How-To-Repeat:
see above

Maybe the makefile should be modified to have the headers
depend on the thread_builddir:
