	* Redid configuration scheme.  Removed gdb.t*/configure.in.
	Renamed gdb.t*/in-gdbme* to gdb.t*/gdbme*.  Changed to use CC, CXX
	instead of CC_FOR_TARGET, CXX_FOR_TARGET.  Added mostlyclean and
	distclean targets.  Built executables via .o files.  Adjusted
	tests to account for source files in $(srcdir) rather than
	$(objdir).
	* lib/gdb.exp (runto): Don't expect () after the function name,
	because it may have arguments.
