Hi, Willy
This v4 mainly uses the argv0 suggested by you, at the same time, a new
run-libc-test target is added for glibc and musl, and the RB_ flags are
added for nolibc to allow compile nolibc-test.c without <linux/reboot.h>
for glibc, musl and nolibc (mainly for musl-gcc, without -I
/path/to/sysroot).
This patchset is based on the 20230705-nolibc-series2 branch of nolibc
repo [2], it must be applied after our v6 __sysret series [3] (argv0
exported there) and Thomas' chmod_net removal patchset [4] (the new
chmod_argv0 is added at the same line of chmod_net, will conflict).
This patchset assumes the chmod_net removal patchset will be applied at
first, if not, the chmod_argv0 added alphabetically will not be applied.
Since our new chmod_argv0 is exactly added to replace chmod_net, so,
Willy, is it ok for you to at least apply the chmod_net removal patch
[5] before this patchset?
selftests/nolibc: drop test chmod_net
This patchset is tested together with the v6 __sysret series [3]:

If use tinyconfig + basic console options (means disable all of the
other options, include procfs, shmem, tmpfs, net and memfd_create, to
save test time, only randomly choose 4 archs):

Changes from v3 --> v4:
* selftests/nolibc: stat_fault: silence NULL argument warning with glibc
selftests/nolibc: gettid: restore for glibc and musl
selftests/nolibc: add _LARGEFILE64_SOURCE for musl
selftests/nolibc: fix up int_fast16/32_t test cases for musl
selftests/nolibc: fix up kernel parameters support
selftests/nolibc: link_cross: use /proc/self/cmdline
tools/nolibc: add rmdir() support
selftests/nolibc: add a new rmdir() test case
selftests/nolibc: fix up failures when CONFIG_PROC_FS=n
selftests/nolibc: prepare /tmp for tmpfs or ramfs
selftests/nolibc: vfprintf: remove MEMFD_CREATE dependency
No change.
* selftests/nolibc: add run-libc-test target
New run and report for glibc or musl. for musl, we can simply issue:
$ make run-libc-test CC=/path/to/musl-install/bin/musl-gcc
* tools/nolibc: types.h: add RB_ flags for reboot()
selftests/nolibc: prefer <sys/reboot.h> to <linux/reboot.h>
Required by musl to compile nolibc-test.c without -I/path/to/sysroot
* selftests/nolibc: chdir_root: restore current path after test
restore current path to prevent breakage of using relative path
* selftests/nolibc: stat_timestamps: remove procfs dependency
selftests/nolibc: chroot_exe: remove procfs dependency
selftests/nolibc: add chmod_argv0 test
use argv0 instead of '/init' as before.
Best regards,
Zhangjin
