I ran into this problem when I had a minimal Linux kernel compiled on a
replicator boot disk. It had SOCKET support left out, and I got a cryptic
error message.

This would fix it.

I won't argue about rejection of this patch. I just sen this mail to tell
you that I wasn't doing a cross compile, but used a precompiled binary
on a reduced kernel, and got confused about the error message. I
investigated what went wrong and came up with this fix to let the binary
decide which to use if socketpair isn't available.

There might be other situtations where a socketpair might fail that I can't

Anyways. Thanks for reply.
