Patch: FYI: remove debugging prints

[Tom Tromey]

I'm checking this in to Classpath, svn head libgcj, and the 4.1 branch
of libgcj.

Phil Muldoon noticed that java.util.prefs was printing stuff to the
console while operating.  This is an ancient leftover -- that we've
never seen this before seems to indicate that prefs is very rarely
used.
