I would like to withdraw this patch.

It appears nobody has been running a MAKEALL with USE_PRIVATE_LIBGCC
enabled for a long, long time.  There are a number of other places
that show similar problems.  Instead of fixing these one by one, I
think we should rather bundle this.

I'm working on a more complete patch (or patch series).

Best regards,

Wolfgang Denk
