* breakpoint.c (remove_breakpoint): Change error to warning so

Browse Source 
that hardware watchpoint removal problems won't leave breakpoint
	traps in the target.
	* configure configure.in:  Make --enable-gdbtk be the default.
	* remote-e7000.c (e7000_insert_breakpoint,
	e7000_remove_breakpoint):  Use e7000 based breakpoints, not memory
	breakpoints.
	* (e7000_wait):  Adjust PC back by two when we see a breakpoint to
	compensate for e7000 maladjustment.
	* sparcl-tdep.c (sparclite_check_watch_resources):  Fix logic bug
	which prevented hardware watchpoints from working.
