HPUX: patch for ext/DynaLoader/dl_hpux.xs

By default, doing a "make test" on a dynamically loaded module with
unresolved symbols will result with a useless error message.  Adding
the BIND_VERBOSE flag will add the names of undefined symbols to the
error message already printed to stderr.  This does *not* affect
default operation; only when PERL_DL_NONLAZY is set does it make a
