cracklib: Allow byte order patch to work on older Linux hosts
Older hosts don't have the htobe* and be*toh functions defined. Instead we fall back to checking the endian and calling bswap_* directly. This works on both old and new hosts. Signed-off-by: Mark Hatle <mark.hatle@windriver.com> Signed-off-by: Saul Wold <sgw@linux.intel.com>

+We can't use the endian.h, htobe* and be*toh functions because they are
+not available on older versions of glibc, such as that found in RHEL
+5.9.
+
+Change to checking endian and directly calling bswap_* as defined in
