Comment (by kencu):

 I have some progress to report on this issue. At present, a number of
 versions of llvm and clang build and work quite well on Tiger, and libc++
 as well.

 {{{ld64-97}}} is working, of course (the default), and {{{ld64-127}}}
 builds as well, but there is an issue with the {{{crt1.o}}} file on 10.4
 compared to 10.5 and that would need to be sorted out. The {{{cctools}}}
 installation is current.

 So that basically gives us something like XCode 10 on Tiger, which is
 pretty impressive, except for the linker, and of course, the ever-present
 problem with @rpath.

 I don't know if you could get a newer dyld on Tiger -- at a certain point,
 it becomes Leopard after all :>. -- but who knows, maybe.
