Without this, I got weird ERRORs and those Tcl backtraces you come
to hate, instead of the expected FAILs.  Committed as obvious after
running a failing guality test and obvserving the intended change.
(Well ok, *adding an explanatory comment* is apparently not obvious,
but I'll take that liberty...)

testsuite:
	* lib/gcc-gdb-test.exp (gdb-test): Pass -- as first argument
	to to send_log.


brgds, H-P
