When introducing the generic asm-offsets.h support the dependency
chain for the prepare targets was changed. All build scripts expecting
include/asm/asm-offsets.h to be made when using the prepare target would broke.
With the limited number of prepare targets left in arch Makefiles
the trivial solution was to introduce a new arch specific target: archprepare
The dependency chain looks like this now:
prepare
|
+--> prepare0
|
+--> archprepare
|
+--> scripts_basic
+--> prepare1
|
+---> prepare2
|
+--> prepare3
So prepare 3 is processed before prepare2 etc.
This guaantees that the asm symlink, version.h, scripts_basic
are all updated before archprepare is processed.
prepare0 which build the asm-offsets.h file will need the
actions performed by archprepare.
The head target is now named prepare, because users scripts will most
likely use that target, but prepare-all has been kept for compatibility.
