Yes, we'd like to be able to reference reserved symbols from input linker scripts, e.g. `PROVIDE_HIDDEN(newsym = __ehdr_start)` (where `__ehdr_start` could be any other reserved symbol like `__edata_start__`). This currently fails with `__ehdr_start` being reported as undefined symbol. This is something that both GNU linker handle fine. One use case for this feature is an alternative solution to https://reviews.llvm.org/D26133.
