+Subject: [PATCH] sandbox: Allow "statx" syscall on i386 for glibc 2.33
+
+glibc versions 2.33 and newer use the modern "statx" system call in their
+implementations of stat() and opendir() for Linux on i386.  Prevent failures in
+the sandbox unit tests by modifying the sandbox to allow this system call
+without restriction on i386 when it is available, and update the test suite to
+skip the "sandbox/stat_filename" test in this case as it is certain to fail.
