Not all linkers support linker scripts, e.g. mold doesn't from what I've read because they make the linker slower.Would we really need to support anything other than ld, gold, and lld, though? -- (
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
if you find mold is not faster than other linkers.
