Alexander Fedotov 37e80fbb1c Align libgloss/arm and libc/sys/arm sources: Fix GetCmdLine semihosting directives
Applied changes from the commit 9b11672:

	When simulating arm code, the target program startup code (crt0) uses
	semihosting invocations to get the command line from the simulator. The
	simulator returns the command line and its size into the area passed in
	parameter. (ARM 32-bit specifications :
	http://infocenter.arm.com/help/topic/com.arm.doc.dui0058d/DUI0058.pdf
	chapter "5.4.19 SYS_GET_CMDLINE").

	The memory area pointed by the semihosting register argument is located
	in .text section (usually not writtable (RX)).

	If we run this code on a simulator that respects this rights properties
	(qemu user-mode for instance), the command line will not be written to
	the .text program memory, in particular the length of the string. The
	program runs with an empty command line. This problem hasn't been seen
	earlier probably because qemu user-mode is not so much used, but this can
	happen with another simulator that refuse to write in a read-only segment.

	With this modification, the command line can be correctly passed to the
	target program.

	Changes:
	- newlib/libc/sys/arm/crt0.S : Arguments passed to the
	AngelSWI_Reason_GetCmdLine semihosting invocation are placed into .data
	section instead of .text

		   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.
