[PATCH] Include s12z-opc.h using ../opcodes.

[PATCH] Include s12z-opc.h using ../opcodes.

[Christian Biesinger via gdb-patches]

This file exists in binutils-gdb/opcodes, and nothing in Makefile.in adds this
to the include path.  Default builds work because in-tree readline adds
binutils-gdb/ to the include path (!). However, this is broken when compiling
with system readline.

Other files already use this way to include files in opcodes:
./gdb/lm32-tdep.c:#include "../opcodes/lm32-desc.h"
./gdb/or1k-tdep.h:#include "../opcodes/or1k-desc.h"
./gdb/mep-tdep.c:#include "../opcodes/mep-desc.h"

etc.

Yeah, my guess is that the include path is added when using the in-tree readline to make
#include "readline/readline.h" work.  And it made this include work by chance.

Thanks, the patch LGTM.

Thanks, pushed.

This patch made me realize that moving gdbsupport to top-level is going
to run into this same issue.  I hadn't considered the
--with-system-readline case here :-(

I thought of 3 options:

1. Move all the gdbsupport headers into a subdirectory, either of
   gdbsupport or include.

2. Add a -I for gdbsupport and change how the #includes are written --
   dropping the "gdbsupport/" part.

3. Make a new "readline/readline" directory and move the contents there,
   similar to what is done for gnulib.

On the whole I lean toward plan 3, because it would also let us handle
opcodes includes in a less ugly way.
