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

ba384f6ed9 C++11 thread_local destructors support 
This feature is specifically for the C++ compiler to offload calling
thread_local object destructors on thread program exit, to glibc.
This is to overcome the possible complication of destructors of
thread_local objects getting called after the DSO in which they're
defined is unloaded by the dynamic linker.  The DSO is marked as
'unloadable' if it has a constructed thread_local object and marked as
'unloadable' again when all the constructed thread_local objects
defined in it are destroyed.

b39949d211 ARM: Support loading unmarked objects from cache. 
ARM now supports loading unmarked objects from
the dynamic loader cache. Unmarked objects can
be used with the hard-float or soft-float ABI.
We must support loading unmarked objects during
the transition period from a binutils that does
not mark objects to one that does mark them with
the correct ELF flags.
