preadv/pwritev: bugfix preadv/pwritev syscall should be 5 args
The current uclibc-ng use 4 arguments, and this will cause
ltp-testsuite's preadv/pwritev case failed.
The syscall of preadv/pwritev in current linux-kernel is 5 arguments:
linux/fs/read_write.c:
SYSCALL_DEFINE5(preadv, unsigned long, fd, const struct iovec __user *, vec,
unsigned long, vlen, unsigned long, pos_l, unsigned long, pos_h)
SYSCALL_DEFINE5(pwritev, unsigned long, fd, const struct iovec __user *, vec,
unsigned long, vlen, unsigned long, pos_l, unsigned long, pos_h)
So just update to 5-args-syscall, and off_t could be 32bit or 64bit.
