    debugging: labs: fix and cleanup LTTng lab Makefile
    
    This Makefile has a wrong ${CC} before lttng-gen-tp, perhaps a leftover of
    a former CC=${CC}, which is not needed due to the global CC. However the
    global CC needs 'export' to work, thus add it.
    
    Also remove -I. from the compiler command line as the crc_random-tp.h file
    is local, so it can be included using '#include "..."' which does not need
    -I.
