New Revision: 326580
URL: https://svnweb.freebsd.org/changeset/base/326580
Log:
AUTO_OBJ: For all top-level targets enforce using an OBJDIR.
This will cause an error if the wanted OBJDIR is not writable. Previously it
would cause the files to generate to the source tree. This was too obscure
and
things like buildworld really expect a proper OBJDIR layout.
