 causes an issue. (I might be done by now had I known that.)

 Right, this is why on Tiger, ld64 does not set +llvmXX as a default
 variant and includes this comment:
 {{{
 # We don't set llvmXX as the default variant on Tiger because it would
 introduce a
 # dependency cycle as llvm requires apple-gcc42 and ld64 to build
 correctly.  Users
 # wanting LTO support in ld64 on Tiger can install the +llvm variant after
 llvm
 # has been installed.

 problem report.

 Huh?

 Anyways, r93318
