Fixes for new ARC toolchain

Compilation issues detected with gcc 4.8.5 + uclibc 1.0.16.

arch/arc/Makefile:
  from upstream Linux 4.7
  - disable -fasynchronous-unwind-tables
  - force -gdwarf-2

arch/arc/boot/Makefile:
  from upstream Linux 4.7
  - add -R .note.gnu.build-id to objcopy flags
  - without this, objcopy creates non-working 2GB Image

arch/arc/include/asm/bitops.h:
  from upstream Linux 4.7
  - fix {set,clear,change}_bit and test_and_{set,clear,change}_bit
  - new assembler is not happy about the old asm code

arch/arc/include/asm/irqflags.h:
  - old assembler had built-in constant 'auxienable'
  - new assembler has built-in constant 'aux_ienable'
  - use the actual value 0x40c here, so this works on both

arch/arc/proc/arc700/entry.S:
  - fix off-by-one error with the number of syscalls
    - NR_syscalls == 354
    - (__syscall_end - __syscall_start) / 4 == 355
  - new assembler is not happy about it

arch/arc/proc/arc700/head.S:
  - fix syntax errors in mov instructions
  - new assembler is not happy about them

drivers/ruby/iputil.c:
  - remove unused but set variable 'donez'

drivers/topaz/hbm.c:
  - fix unused but set variable 'rc'

NOTE:
These changes are valid and working for the old toolchain as well.
