This change is necessary to support Cortex-R based chips in RTEMS.

This patch should be applied to GCC 4.8, 4.9 and mainline.  I do not
have write access, so in case this gets approved, please commit it for
me.

2014-07-02  Sebastian Huber  <sebastian.huber@embedded-brains.de>

	* config/arm/t-rtems-eabi: Add
	mthumb/march=armv7-r/mfpu=vfpv3-d16/mfloat-abi=hard,
	mbig-endian/mthumb/march=armv7-r, and
	mbig-endian/mthumb/march=armv7-r/mfpu=vfpv3-d16/mfloat-abi=hard
	multilibs.

I consider this to be RTEMS-specific.  I'll let them decide.
