[OpenAFS-port-darwin] Building on rc9 on intel...

[Chaskiel M Grundman]

The following patch (based on comments relayed to me from Ed by a third 
party, but I was closing in on the problem...) fixes the crash that occurs 
in all LWP-using programs on 10.4.4 on X86.
Ed's patch is likely to be different, since his patchset appears to include 
support for building universal binaries.
