For non-Windows targets, we expect a gcc-compatible linker 
driver, i.e., gcc or clang, and as Jacob pointed out, you can 
choose between them via CC env variable (and a hidden -gcc option 
IIRC).

A while ago, I integrated LLD into LDC itself. It's currently 
only able to link MSVC binaries, so `-link-internally` only works 
for MSVC targets.
There's a PR in which I extended it to ELF and Mach-O targets 
too; it seems to be working after a quick test (if you have the 
required libs obviously), but the needed linker flags normally 
added by gcc makes the command-line explode:

The command-line flags could be added once to the config file 
though if your environment is stable.

Yep, that's what I'd do.
