--- Comment #1 from Jim Wilson <wilson at gcc dot gnu.org> ---
Looks like the problem is in riscv_elf_finish_dynamic_symbol where we have
/* If the symbol is weak, we do need to clear the value.
Otherwise, the PLT entry would provide a definition for
the symbol even if the symbol wasn't defined anywhere,
and so the symbol would never be NULL. */
if (!h->ref_regular_nonweak)
sym->st_value = 0;
The well maintained targets all have check for !h->pointer_equality_needed in
addition to or instead of the !h->ref_regular_nonweak check. It looks like
this pointer_equality_needed check is missing from a lot of ports, but maybe
not all of them support linux shared libraries.
So we need code to set h->pointer_equality_needed correctly based on relocs
seen, and then a simple check to clear sym->st_value if pointer_equality_needed
is zero.
