# Solaris 8's mkdir -p isn't thread-safe.  If you mkdir -p a/b and
# mkdir -p a/c at the same time, both will detect that a is missing,
# one will create a, then the other will try to create a and die with
# a "File exists" error.  This is a problem when calling mkinstalldirs
# from a parallel make.  We use --version in the probe to restrict
# ourselves to GNU mkdir, which is thread-safe.
