Commit 0748cb3e1fbd89c03a98c15e91ad65797981de77

kconfig: add alldefconfig 

alldefconfig create a configuration with all values set
to their default value (form the Kconfig files).

This may be useful when we try to use more sensible default
values and may also be used in combination with
the minimal defconfigs.
