Comment (by Phyx-):

 New linker is making some significant progress here as well

 The LLVM libraries require the new `big-obj` support and also require
 proper section alignment support which now works. The remaining problem is
 that it's C++ and requires proper support for Constructors and Destructors
 via `__DTOR_LIST__` and `__CTOR_LIST__`. However I lack some knowledge of
 how the C++ ABI and linking work so I'll need to read up before I can add
 this.
