Comment(by mfeiri@…):

 The ld64 port should actually use the libLTO library provided by macports.
 Only a "lucky" combination of lazy linking and a relative link path
 covered this bug and an issue in our llvm ports. I'll try to figure out if
 we should fix this the apple way (by removing an install_name_tool patch
 in llvm-X.X) or the unix way (by adding an additional install_name_tool
 patch in ld64). You can see a preview at
 http://macports.feiri.eu/devel/ld64/Portfile (this currently shows the
 unix way).
