ls: improve removed-directory test
    
    * tests/ls/removed-directory.sh: Remove host_triplet test.
    Skip this test if one cannot remove the working directory.
    From a suggestion by Bernhard Voelker (Bug#39929).

ls: restore 8.31 behavior on removed directories
    
    * NEWS: Mention this.
    * src/ls.c: Do not include <sys/sycall.h>
    (print_dir): Don't worry about whether the directory is removed.
    * tests/ls/removed-directory.sh: Adjust to match new (i.e., old)
    behavior.

+* Noteworthy downstream changes (on top of upstream coreutils-8.32)
+
+** Changes in behavior
+
+  On GNU/Linux systems, ls no longer issues an error message on
+  directory merely because it was removed.  This reverts a change
+  that was made in release 8.32.

 * Noteworthy changes in release 8.32 (2020-03-05) [stable]
