commit 9bbf6f91c6e85ca916ec2c266009167f20f5ecfd
Author: Mike Frysinger <vapier@gentoo.org>
Date:   Mon Jan 4 04:06:01 2016 -0500

    sim: punt x86-specific bswap logic
    
    The compiler/C library should produce reasonable code for htonl/ntohl,
    and at least glibc tries pretty hard to always produce good code for
    them.  This logic only had support for 32-bit x86 systems anymore, and
    it's unlikely people were even opting into this, so drop it all.
