string concatenation in gas

[Timothy Wall]

I implemented a .eval/.asg for the tic54x target (which save evaluated
quantities as strings which then get interpreted by the assembler); I actually
had to have this functionality for that target's compatibility.  Actually, I
think the ".break" was local to that target as well...
