Clean build tree required: waf changes

[Andrew Bartlett]

Just a reminder to those hitting strange build errors in master, that
some patches by metze to simplify waf have landed.  If you get errors
like

source4/librpc/gen_ndr/tables.c:7:47: fatal error:
default/librpc/gen_ndr/ndr_wzcsvc.h: No such file or directory
#include "default/librpc/gen_ndr/ndr_wzcsvc.h"

Then 'rm -rf bin' in your build tree and a re-configure, rebuild will
help.

Thanks,

Andrew Bartlett
