That actually appears to be a list of issues with non-Linux hosts, not non-Linux targets. I would certainly hope both LTO and gold should work on a wide range of non-Linux hosts (if anyone cares to contribute patches for such support), including non-ELF hosts, even though restricted to ELF targets at least in the case of gold. libelf definitely works on MinGW and Solaris hosts. -- Joseph S.
