Fix for thumb_div_mod_body

Hi,

When building the llvm-gcc frontend for an ARM cross compiler I ran into the
following error:

-c ../../llvm-gcc4.2-2.3.source/gcc/config/arm/lib1funcs.asm -o
libgcc/thumb/_udivsi3.o
../../llvm-gcc4.2-2.3.source/gcc/config/arm/lib1funcs.asm: Assembler messages:
../../llvm-gcc4.2-2.3.source/gcc/config/arm/lib1funcs.asm:847: Error: bad
instruction `thumb_div_mod_body 0'

It seems that apple's arm assembler behaves differently.  Changing
THUMB_DIV_MOD_BODY 0 into THUMB_DIV_MOD_BODY(0) seems to fix the problem when
using the standard arm assembler from binutils.
