I filed the bug not to find an alternative solution. I am wary of the semantics
of --export-dynamic, --dynamic-list (and contributed the recent
--export-dynamic-symbol --export-dynamic-symbol{,-list} BTW).

First, this is already a problem with --allow-shlib-undefined. Now the question
is whether it is also a problem of --no-allow-shlib-undefined. My reasoning is
that placing a shared object on the linker command line is an explicit
intention that its referenced symbols should be exported, even if the shared
object itself is unneeded (in terms of --as-needed).
