[PATCH] S12Z: gas: Fix bug when a symbol name was the single letter 'c'.

This sounds like it might be a more serious problem...

How does the assembler know that "c" here is meant to be label c 
and not the register c ?

(In other architectures it is often common practice for the compiler
to prefix all user generated symbols with a character, usually an
underscore, so that it is possible to distinguish between register
names and user symbols).
