Patch for malloc/mtrace.c

[Mark Kettenis <kettenis at wins dot uva dot nl>]

I'm having a bit of a problem with the use of fopen64 in
malloc/mtrace.c:

1. The Hurd doesn't have fopen64.

2. The use of fopen64 pollutes the ISO C namespace.

While I can solve (1) by implementing fopen64 in GNU stdio, and it can
be argued that (2) isn't an issue, since mtrace() itself isn't ISO C,
I'd personally still prefer using the attached patch to solve the
problem.
