#9 use of llseek om 64bit

[Michal Suchanek]

  The  _llseek()  system  call  repositions  the  offset of the open file description associated with the file
   descriptor fd to (offset_high<<32) | offset_low bytes relative to the beginning of  the  file,  the  current
   file offset, or the end of the file, depending on whether whence is SEEK_SET, SEEK_CUR, or SEEK_END, respec-
   tively.  It returns the resulting file position in the argument result.

   This system call exists on various 32-bit platforms to support seeking to large file offsets.

This is not intended to be used on 64bit systems and is not well-defined there.

x86_64 is covered by xmview-os/xmview/defs_x86_64_um.h:#define NRllseek __NR_doesnotexist

Attaching patch.

The r_llseek is defined even when NRllseek == __NR_doesnotexist so it should compile.

Not tested.
