I just double-checked and it seems Nix has a workaround to remove the
--dynamic-linker flag before building the kernel. As I was
hand-compiling the kernel rather than installing it from Nix, the
workaround did not get applied.

Regarding this, I just think the difference in behavior between ld.lld
and ld.bfd is severe enough that handling this edge case is warranted.

I am happy to leave this patch out though, or add something minimal like
a conditional check to add --no-dynamic-linker if the linker is ld.lld.
