I created a

config LTT_FAST_SERIALIZE
        tristate "Linux Trace Toolkit Custom Serializer"
        default y
        help
          Library for serializing information from custom, efficient, tracepoint
          probes.

which insures LTT_USERSPACE_EVENT and LTT_KPROBES do not depend on
LTT_TRACEPROBES anymore.
