patch to fix the bug

Hi all，
  I found the latest glibc do not provide  posix_fadvise64  when static
linking. 
  It's very easy to reproduce the bug.
  Compile the following code using "-static -D_FILE_OFFSET_BITS=64 -mabi=64",
ld will report " undefined reference to `posix_fadvise64'".
#include <fcntl.h>
int main()
{
        posix_fadvise(0,0,0,0);
        return 0;
}
  The fix is quite simple as well, just two new lines in
sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fadvise64.c. see the attached
file for details.
