PATCH: Use x86-64 bits/byteswap.h for both i386 and x86_64

[Roland McGrath]

> x86_64/bits/byteswap.h is i386-compatible.  There is nothing to do.

I see.  I misread your message then.  Using git diff -M for patches that
do file renames makes it much more clear when a rename is verbatim,
and that would have prevented my misunderstanding.

So now I think this change is fine.  But I'd like Joseph to sign off too.


Thanks,
Roland
