Main.log from PPC Tiger

[kencu (Ken)]

options here are to change all of the various builds to not use rpaths, which is getting increasingly impractical, ...or to find a way for Tiger to absorb the flag.

Tiger doesn't have the dyld support to use rpaths. but the flag could be translated into something Tiger can use, probably with a shell script wrapper, that might work for the majority of cases.
