From: Anthony PERARD <anthony.perard@gmail.com>

File "include/config/auto.conf" and "include/config/auto.conf.cmd"
should be included from the build tree even if they are present in the
source tree. Avoiding to use make's command line option --include-dir
will have make include the right "auto.conf" file. But that mean we
now need to specify $(srctree) for all other Makefile we include.
