ARM gcc 4.3.3 fix and armv5 .ltorg

[Xerxes Rånby]

Hi the following patch will re-enable compilation of the cppInterpreter_arm.S using GCC 4.3.3.

The second part will unbreak the armv5 buildbots where they currently complain that
bytecodes_arm.s:2717: Error: invalid literal constant: pool needs to be closer

the problematic opcode block of the generated bytecodes_arm.s then looks like this:
@-----------------------------------------------------------------------------
         .macro  iaccess_0       jpc_off=0, seq_len=4
...
  DISPATCH_FINISH
         .endm

         Opcode  iaccess_0
         iaccess_0               <---  line 2717


the patch will fix the compile error by turning the generated opcode block into:
@-----------------------------------------------------------------------------
         .macro  iaccess_0       jpc_off=0, seq_len=4
...
  DISPATCH_FINISH
         .endm

         Opcode  iaccess_0
         iaccess_0
	.ltorg


OK to push into icedtea6 HEAD?
Cheers
Xerxes
