Patch to add fopen/fopen64 declarations to bfd

[Steve Ellcey]

My build of binutils recently started failing when a use of fopen64 was
added because, while IA64 HP-UX has a fopen64 function in libc, it does
not make the declaration visible unless _LARGEFILE64_SOURCE is defined.
So I get an error since it uses fopen64 but it didn't see a declaration
for fopen64.

This patch fixes the problem by checking for a fopen64 declaration and
inserting one if it doesn't find it.  I also did the same change for
fopen just to make those functions consistent.

Tested on IA64 HP-UX, OK for checkin?
