In commit 3dd4d40b420846dd35869ccc8f8627feef2cff32 ("xfs: Sanity check
flags of Q_XQUOTARM call"), Linux 5.4 added checking for the flags
argument, causing the test to fail due to too restrictive test
expectations.

This patch fixes some test-errno-linux unexpected returns for the
tested syscalls on some older kernels (I saw it on a Linux 3.8 on
armv7l). Basically:
- inotify_add_watch: Linux v3.8 (676a0675c) removed the test to
check at least one valid bit in flags (to return EINVAL). It
was later added back in v3.9 (04df32fa1).
- quotactl: returns ENOSYS for kernels not configured with
CONFIG_QUOTA.
Checked on x86_64-linux-gnu and armv7l-linux-gnueabihf.
* sysdeps/unix/sysv/linux/test-errno-linux.c (do_test): Handle
non expected inotify_add_watch and quotactl return.
This patch fixes multiple issues of test-errno.c (9a56f87183):
- Rename Linux test-errno.c to test-errno-linux.c to avoid build
the same source for both tests.
- Add a mlock check for 32 bits build running on 64 bits kernels.
Althuough man pages states that mlock fails with EINVAL if final
address overflows, kernels does not return it for aforementioned
condition (it returns ENOMEM instead). Although it seems to be
a kernel issue for compat syscall handling, I think it is worth
to still check syscall return and document the behavior.
- Initialize option lenght for setsockopt check.
- Change open test from EINVAL to EISDIR.
Checked on x86_64-linux-gnu and i686-linux-gnu (running on 64 bits
kernel).
* posix/test-errno.c (do_test): Initialize setsockopt optlen.
* sysdeps/unix/sysv/linux/test-errno.c: Move to ...
* sysdeps/unix/sysv/linux/test-errno-linux.c: ... here.
(test_wrp_rv): Fix format.
(test_wrp_rv2): New macro.
(do_test): Handle mlock return on 64 bits kernels with 32 bits
binaries.
