[LLVMdev] RFC: I plan to remove the autoconf and Makefile build of LLD

Just out of curiosity. The community generally seems to be moving away from autoconf toward CMake. Is there a reason why you need the autoconf build bad enough to support it out-of-tree?
Today supporting LLD’s autoconf build out-of-tree probably isn’t that bad because LLD is fairly small and LLVM still has a functioning autoconf build system. However, if LLVM moves off autoconf (and you’re stuck on it for some reason) you may be in the awful position of needing to support LLVM’s autoconf build out-of-tree, which would be pretty terrible.
If there is a deficiency in the CMake build system that keeps you from using it, we should track that as a blocker for removing autoconf from LLVM and address it.
