ld: Add more tests for --as-needed Prior to commit 1e3b96fd6cf0c7d018083994ad951ccf92aba582 Author: Alan Modra <amodra@gmail.com> Date: Fri Sep 4 13:54:21 2020 +0930 Allow plugin syms to mark as-needed shared libs needed when removing unused IR symbol references, ld didn't add unnecessary DT_NEEDED libraries which may lead to undefined symbol reference in a --as-needed library when the symbol is defined in a prior --as-needed library and there is no reference in relocatable inputs. This behavior is desirable since it ensures that both lazy and non-lazy bindings work the same way. The problem is with --as-needed libraries, which happens with and without LTO. Now, the linker may add many unnecessary DT_NEEDED libraries for IR inputs.
