> The gold linker is significantly faster than gnu ld.
> There is some way to get gcc and clang to link using gold instead of gnu ld, without replacing ld with gold system-wide. The benefit to this is that gnu ld is still required to build certain things, such as kernel modules.
> So what is the magical incantation?
> * For GCC, looks like it's: gcc -fuse-ld=gold
> * For Clang, maybe: clang -use-gold-plugin
