Default name of target executable

These kinds of answers are all too abundant, no offense meant. :-)
There are lots of things that *can* be done already, that doesn't mean
that we can't improve them!

Using a shell script is a possible work-around, but certainly not
*the* solution. If there is no real reason for ghc to spit out a.out
files, then surely choosing the exe name from the main input file
would simplify a programmer's life. And for applications that
desperately want a.out, well, there's still the -o flag, right?

I second Tomasz suggestion.
