    It is now possible to assign options to AS, CC and LD
    on the command line - which is only used when building modules.
    
    {A,C,LD}FLAGS_MODULE was all used both in the top-level Makefile
    in the arch makefiles, thus users had no way to specify
    additional options to AS, CC, LD when building modules
    without overriding the original value.
    
    Introduce a new set of variables KBUILD_{A,C,LD}FLAGS_MODULE
    that is used by arch specific files and free up
    {A,C,LD}FLAGS_MODULE so they can be assigned on
    the command line.
    
    All arch Makefiles that used the old variables has been updated.
    
    Note: Previously we had a MODFLAGS variable for both
    AS and CC. But in favour of consistency this was dropped.
    So in some cases arch Makefile has one assignmnet replaced by
    two assignmnets.
    
    Note2: MODFLAGS was not documented and is dropped
    without any notice. I do not expect much/any breakage
    from this.
