The gcc.dg/sso tests gratuitously fail on PTX because they use IO facilities 
that don't exist there.  This  patch changes the dumping to use the putchar 
function call (and not a macro), and not use fputs.

With this they all pass.

I'm not quite sure where the maintainer  boundaries lie for this kind of fix. 
Any objections?
