[patch] New option --disable-reenterable-atexit

Subject: [patch] New option --disable-reenterable-atexit
Authentication-results: sourceware.org; auth=none

There is an existing macro to declare atexit data structure as global
variables, so that it can be discarded if not used to save memory
consumption. But this macro was only enabled for certain targets.

This patch adds an configure option --disable-reenterable-atexit for more
targets.

ChangeLog:
2013-10-16  Joey Ye  <joey.ye@arm.com>

	configure.in (disable-reenterable-atexit): New option.
	configure: Regenerated.
	newlib.hin (_REENT_GLOBAL_ATEXIT): Place-holder.
	README (disable-reenterable-atexit): Description for
	new option.
