Masahiro Yamada 331b45fb70 kbuild: Fix a false error of generic board support 
Before this commit, make terminated with an error
where is shouldn't under some condition.

This bug happened when we built a board unsupporting
generic board right after building with generic board.

For example, the following sequence failed.
(harmony uses generic board but microblaze-generic does not
support it)

  $ make harmony_config
  Configuring for harmony board...
  $ make CROSS_COMPILE=arm-linux-gnueabi-
    [ Build succeed ]
  $ make microblaze-generic_config
  Configuring for microblaze-generic board...
  $ make CROSS_COMPILE=microblaze-linux-
  Makefile:488: *** Your architecture does not support generic board.
  Please undefined CONFIG_SYS_GENERIC_BOARD in your board config file.  Stop.

We had to do "make clean" before building the microblaze board.

This commit fixes this unconvenience.

Move generic board sanity check to "prepare1" target,
which is run after generation of include/autoconf.mk.

# Most importantly: sub-Makefiles should only ever modify files in

# turn into vmlinux), we will call a sub make in that other dir, and
# after that we are sure that everything which is in that other dir
# is now up to date.

# The only cases where we need to modify files which have global
# effects are thus separated out and done before the recursive
# descending is started. They are now explicitly listed as the
