LLD doesn't make any guess on --dynamic-linker value. If it is not present,
we don't add an .interp section at all, and that's it. We are not aiming
precise 100% compatibility with the exiting linkers -- if there is
something that can be simplified, we'd at least try. Compiler driver
already passes bunch of -L options to the linker, so requesting the
compiler driver to pass all of them does not sounds like an unreasonable
request to me.
