Pedro Alves cf6de44d75 gdb/: Require a C++ compiler 
This removes all support for building gdb & gdbserver with a C

	* NEWS: Mention that a C++ compiler is now required.
	* Makefile.in (COMPILER, COMPILER_CFLAGS): Remove.

configure.

Mike Frysinger b835bb5265 gdb: split out warnings helpers 
This will allow the sim tree to use the same set of warnings.
The new code in warning.m4 is exactly the same (other than the
AC_DEFUN wrapping).
