The line



in dub.sdl

enables me to change linker for LDC.

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.

dub links using the compiler, so it basically just runs `dmd 
[flags] [files-to-link]`

In the DMD documentation you can see that it just runs gcc: 
https://dlang.org/dmd-linux.html#linking

Personally I always `ln -s /usr/bin/ld.gold /usr/local/bin/ld` to 
make ld.gold the default.

There's an environment variable "CC" that can be used to select which C 
compiler is used. 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.
