    libpayload: fix compiler flags
    
    lpgcc was unconditionally setting -m32.
    
    Most of the flags it sets in the common case are right, however: no need
    to duplicate them everywhere, and we only want to change the common ones
    in one place, so it would be a shame to duplicate _CFLAGS all over the place.
    
    So add another variable, _ARCHEXTRA, which can be used to add
    special flags to _CFLAGS. We onlu use it at present for the x86; this may
    change.
    
    This allows us to get through compiling on arm and x86.
