Hi!

So far I think none of the 32-bit big endian arches support this syscall
(and ppc32 will likely need its own implementation of this, as it requires
long long args to be at padded to even arguments), but certainly it doesn't
hurt to follow what linux/posix_fadvise{,64}.c is already doing.

	* sysdeps/unix/sysv/linux/sync_file_range.c (sync_file_range): Use
	__LONG_LONG_PAIR macro.
