Subject: [PATCH v2 0/7] nolibc: add generic part1 of prepare for rv32

Hi, All

Thanks very much for your review suggestions of the v1 series [1], this
is the generic part1 of the v2 revison.

* selftests/nolibc: syscall_args: use generic __NR_statx

    A more generic statx is used instead of fstat

    (Review suggestions from Willy, Arnd)

* selftests/nolibc: allow specify extra arguments for qemu

    Besides BIOS, QEMU_ARGS_EXTRA is better for more requirements

    (Review suggestions from Thomas, Willy)

* selftests/nolibc: fix up compile warning with glibc on x86_64

    Definition of uint64_t differs from glibc and nolibc, use the right
    print format here

* selftests/nolibc: not include limits.h for nolibc

    Remove the requirement of limits.h for nolibc can let us use older
    glibc for rv32

    (Review suggestions from thomas)

* selftests/nolibc: use INT_MAX instead of __INT_MAX__

    A trivial cleanup, based on the previous patch

* tools/nolibc: arm: add missing my_syscall6

    Required by future forced pselect6/pselect6_time64, tested on arm/vexpress-a9

    (Review suggestions from Arnd)

* tools/nolibc: open: fix up compile warning for arm

    A trivial fixup based on compiler's suggestion and glibc code

Best regards,
Zhangjin
