	* sysdeps/arm/dl-machine.h (elf_machine_dynamic): Ditto.
	(elf_machine_load_address): Clear T bit of PLT entry contents.
	(RTLD_START): Mark function symbols as such.  Tweak pc-relative
	addressing to avoid depending on pc read pipeline offset.
	* sysdeps/arm/machine-gmon.h (MCOUNT): Add Thumb-2 implementation.
	* sysdeps/arm/tls-macros.h: Add alignment for Thumb-2.
	(ARM_PC_OFFSET): Define.
	(TLS_IE): Define differently for Thumb-2.
	(TLS_LE, TLS_LD, TLS_GD): Use ARM_PC_OFFSET.
	* sysdeps/arm/elf/start.S: Switch to thumb mode for Thumb-2.
	* sysdeps/unix/sysv/linux/arm/eabi/sysdep.h (INTERNAL_SYSCALL_RAW):
	Add Thumb implementation.
	* sysdeps/unix/sysv/linux/arm/eabi/nptl/aio_misc.h: New.
	* sysdeps/unix/sysv/linux/arm/eabi/nptl/unwind-resume.c: Enforce
	alignment for Thumb-2.  Adjust offset from PC for Thumb-2.
	* sysdeps/unix/sysv/linux/arm/eabi/nptl/unwind-forcedunwind.c: Ditto.
	* sysdeps/unix/sysv/linux/arm/nptl/bits/atomic.h (atomic_full_barrier,
	__arch_compare_and_exchange_val_32_acq): Add Thumb-2 implementation.
