* ftruncate64 syscall. Copes with 64 bit and 32 bit machines
* and on 32 bit machines this sends things into the kernel as
* two 32-bit arguments (high and low 32 bits of length) that
* are ordered based on endianess. It turns out endian.h has
* just the macro we need to order things, __LONG_LONG_PAIR.
