RFC: ARM GCC changes

[Sebastian Huber]

Hi,

I propose a change of the RTEMS configuration for ARM GCC:

	o the target arm-rtemseabi4.11 should be renamed to arm-rtems4.11
	  providing the up to date ARM EABI version 5 tool chain,
	o the target arm-rtemself4.11 provides the obsolete GNU EABI (also
	  known as ARM ELF) variant.

The patches are attached.

GCC test suite results for arm-rtems4.11:

http://gcc.gnu.org/ml/gcc-testresults/2012-05/msg00324.html

RTEMS test suite results for arm-rtems4.11 follow.

The changes in the RTEMS test suite need further examination.

This is the proposed ARM GCC tool chain for RTEMS 4.11.  The arm-rtemself 
should be removed as soon as possible.
