Simon Marchi 2b8d134be4 sim: set ASAN_OPTIONS=detect_leaks=0 when running igen and opc2c
The igen/dgen and opc2c tools leak their heap-allocated memory (on
purpose) at program exit, which makes AddressSanitizer fail the tool
execution.  This breaks the build, as it makes the tool return a
non-zero exit code.

Fix that by disabling leak detection through the setting of that
environment variable.

I also changed the opc2c rules for m32c to go through a temporary file.
What happened is that the failing opc2c would produce an incomplete file
(probably because ASan exits the process before stdout is flushed).
This meant that further make attempts didn't try to re-create the file,
as it already existed.  A "clean" was therefore necessary.  This can
also happen in regular builds if the user interrupts the build (^C) in
the middle of the opc2c execution and tries to resume it.  Going to a
temporary file avoids this issue.

sim/m32c/ChangeLog:

	* Makefile.in: Set ASAN_OPTIONS when running opc2c.

sim/mips/ChangeLog:

	* Makefile.in: Set ASAN_OPTIONS when running igen.

sim/mn10300/ChangeLog:

sim/ppc/ChangeLog:

	* Makefile.in: Set ASAN_OPTIONS when running igen.

sim/v850/ChangeLog:

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
