[LLVMdev] IMPORTANT: llvm-ar requirements

[Reid Spencer]

This problem has been fixed. It is now possible to link against archives
created with ar (instead of llvm-ar). Doing so will slow down the link,
but at least it works.  The instructions below requesting use of
llvm-ranlib are not *necessary* but they are *advised*.
