PATCH: avoid glibc conflict

[Keith M Wesolowski <wesolows@foobazco.org>]

This is needed to avoid a conflict with glibc on bigendian platforms
when -O or higher is specified.  It's already in 2.6, and I'm not sure
why it hasn't been seen in 2.4.  The symptom is that this program will
not compile with -O2:

#include <asm/byteorder.h>
#include <netinet/in.h>
int main () { }

Here's the patch.
