Looking at the termination of t_immutable test program:
ARM:
mprotect(0xffff86092000, 4096, PROT_READ) = 0
mprotect(0xffff860b3000, 4096, PROT_READ) = 0
munmap(0xffff86295000, 38279) = 0
openat(AT_FDCWD, "/etc/passwd", O_RDONLY|O_CLOEXEC) = 4
lseek(4, 0, SEEK_CUR) = 0
fstat(4, {st_mode=S_IFREG|0644, st_size=1682, ...}) = 0
mmap(NULL, 1682, PROT_READ, MAP_SHARED, 4, 0) = 0xffff8629e000
lseek(4, 1682, SEEK_SET) = 1682
munmap(0xffff8629e000, 1682) = 0
close(4) = 0
dup(2) = 4
fcntl(4, F_GETFL) = 0x20002 (flags O_RDWR|0x20000)
fstat(4, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0), ...}) = 0
write(4, "acl: Function not implemented\n", 30acl: Function not implemented
) = 30
close(4) = 0
exit_group(1) = ?
+++ exited with 1 +++
x86 at same place:
mprotect(0x7f677e46f000, 4096, PROT_READ) = 0
mprotect(0x7f677e67d000, 4096, PROT_READ) = 0
munmap(0x7f677f097000, 165753) = 0
openat(AT_FDCWD, "/etc/passwd", O_RDONLY|O_CLOEXEC) = 4
lseek(4, 0, SEEK_CUR) = 0
fstat(4, {st_mode=S_IFREG|0644, st_size=3023, ...}) = 0
mmap(NULL, 3023, PROT_READ, MAP_SHARED, 4, 0) = 0x7f677f0bf000
lseek(4, 3023, SEEK_SET) = 3023
munmap(0x7f677f0bf000, 3023) = 0
close(4) = 0
fsetxattr(3, "system.posix_acl_access",
"\2\0\0\0\1\0\6\0\377\377\377\377\2\0\6\0\376\377\0\0\4\0\6\0\377\377\377\377\20\0\6",
44, 0) = -1 EOPNOTSUPP (Operation not supported)
fsetxattr(3, "trusted.test", "readonly", 8, XATTR_CREATE) = 0
fsetxattr(3, "user.test", "readonly", 8, XATTR_CREATE) = 0
..etc
So it's something different in the test program in the acl handling side

zfs returns enosys when calling fsetxattr

Bug description:
When xfstests are run on zfs, they expect acl calls (like fsetxattr)
to either work or return ENOTSUP. zfs fails with ENOSYS, at least on
arm64.
The result on calling the immutable tests of xfstests are:
acl: Function not implemented
