Include the explanation from my cae9400 patch in the perldelta so that
it can be understood when read stand-alone.
File::Copy skips suid tests on a nosuid partition (cae9400)
+These tests were being skipped on OpenBSD, but nosuid partitions can
+exist on other systems too. Now it just checks if it can create a suid
+directory, if not the tests are skipped.
+
+Perl builds without errors in a nosuid /tmp with this patch.
