The AC_PROG_MKDIR_P() macro is supposed to check for a race-free mkdir(1).
NetBSD's is race-free but is not detected as such.

Basic test case is attached. When configure is run, I get:

checking for a race-free mkdir -p... ./install-sh -c -d

Looking at the generated configure code, the test seems to consist of running
'mkdir --version' and comparing the result to a few known-good values. This
fails on NetBSD since NetBSD's mkdir does not support --version.

Looking at the FreeBSD and OpenBSD and macOS man pages, --version is not
supported either, so this will fail in the same way there.
