365261c37f arm: Mark assembly files that will not use thumb mode 
Some routines are written with complex LDM/STM insns that cannot be
used in thumb mode, or are highly conditional requiring excessive
IT insns.

When a future patch goes in to enable thumb2 by default, this marker
will be used to override that default.

6ccd0107f3 arm: Add IT insns for thumb mode 
These are ignored by the assembler in ARM mode, so by
default this has no effect on generated code.

60812ba09d arm: Update preconfigure fragment for gcc 4.8 
New defines from gcc 4.8:
 #define __ARM_ARCH_ISA_ARM 1
 #define __ARM_ARCH_PROFILE 65
 #define __ARM_ARCH_ISA_THUMB 2
 #define __ARM_ARCH 7

all of which got in the way of the one we wanted:
 #define __ARM_ARCH_7A__ 1
