Re: Choosing a non-default linker for dmd (via dub)

Is there any equivalence for selecting the linker, "LD" perhaps? You normally just add -fuse-ld=gold to the C compiler cmdline, e.g., via -Xcc=-fuse-ld=gold in the DMD cmdline.

Is it possible to choose a specific linker for DMD aswell in a similar way? I only find the flag `-L` that sets flags but no linker executable. One way is to link /usr/bin/ld to either /usr/bin/ld.gold or /usr/bin/ld.lld but it would be nice to be able to do this from the dub.sdl or the command-line call to dub.
