Android should use 64-bit LFS symbols for `lseek` and `ftruncate`, lest those offset parameters suffer a lossy cast down to a 32-bit `off_t`. Unlike GNU/Linux, Android's `stat`, `dirent`, and related functions are always 64-bit LFS compatible, and `open` already implies `O_LARGEFILE`, so all those don't need to follow Linux. It might be nice to unify them anyway, but those other LFS symbols aren't present in API 18 bionic. r? @alexcrichton
