[patch] use glibc's <endian.h>

["Steve M. Robbins" <steven.robbins@xxxxxxxxxxxx>]

Hi,

I maintain OpenInventor for Debian.  We build on a large number
of different CPUs.  Rather than add a bunch more "#if __cpu__"
stanzas to the inventor header "machine.h", I patched it to
use the GNU libc header <endian.h> as a fall-back.

Regards,
-Steve
