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.
