    Fixed incorrect LLONG alignment for openrisc and cris
    
    OpenRISC (or1k) has long long alignment to 4 bytes, but currently not
    defined in abitypes.h. This lead to incorrect packing of /epoll_event/
    structure and eventually infinite loop while waiting for file
    descriptor[s] event[s].
    
    Fixed also CRIS alignments (1 byte for all types).
