profiling fails on arm-linux

[Philip Blundell <pb at futuretv dot com>]

Compiling even trivial files such as "foo() { }" seems to fail with profiling 
enabled on ARM.

/home/pb/c.i:0: Internal compiler error in get_insn_template, at final.c:2069
   Please submit a full bug report.

This is the offending call to get_insn_template.

  if (profile_flag || profile_block_flag)
    {
      /* It's best if we can write a nop here since some
	 assemblers don't tolerate zeros in the text section.  */
      output_asm_insn (get_insn_template (CODE_FOR_nop, NULL), NULL_PTR);
    }
