We can choose to not package mold of course, but I think it would be a 
good idea to support mold, because it appears to be much faster than the 
others. Furthermore, I'd like to eventually switch to mold by default, 
because it's much faster.  From the README:

mold is so fast that it is only 2x /slower/ than |cp| on the same 
machine. Feel free to file a bug <https://github.com/rui314/mold/issues> 
if you find mold is not faster than other linkers.

Program (linker output size) 	GNU gold 	LLVM lld 	mold
Chrome 96 (1.89 GiB) 	53.86s 	11.74s 	2.21s
Clang 13 (3.18 GiB) 	64.12s 	5.82s 	2.90s
Firefox 89 libxul (1.64 GiB) 	32.95s 	6.80s 	1.42s
