Hi

     I finally spent some more time on the the libstdc++.exp file and 
have several remarks about it:

- I have added a 'file delete $exe' in debug more check target recently 
but in several other places there are 'remote_file build delete $exe', 
shouldn't I use the remote version instead ?
- Many check targets are using a simple compilation process that could 
even be limited to the preprocessing stage. I think I am going to change 
the executable compile type in preprocess.
- Most of the time we do not use the result of the build (compilation or 
preprocessing). Couldn't we give '/dev/null' as the output ? Is it 
portable enough ?
