	* sysdeps/arm/sysdep.h: Define __USE_BX__ if bx is available.
	Use it instead of __THUMB_INTERWORK__.  Make RETINSTR take
	only a condition and a register.
	* sysdeps/arm/dl-machine.h: Use __USE_BX__ instead of
	__THUMB_INTERWORK__.
	(_dl_start_user): Use BX.
	* sysdeps/arm/strlen.S: Use DO_RET.
	* sysdeps/unix/arm/brk.S, sysdeps/unix/arm/fork.S,
	sysdeps/unix/arm/sysdep.S, sysdeps/unix/arm/sysdep.h: Likewise.
	* sysdeps/unix/sysv/linux/arm/clone.S,
	sysdeps/unix/sysv/linux/arm/mmap.S,
	sysdeps/unix/sysv/linux/arm/mmap64.S,
	sysdeps/unix/sysv/linux/arm/socket.S,
	sysdeps/unix/sysv/linux/arm/sysdep.h,
	sysdeps/unix/sysv/linux/arm/vfork.S: Update uses of RETINSTR.
