--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think this is a BFD linker bug, with --dynamic-list the linker resolution
with
GNU ld 2.30 is the following

while when using gold it is

which looks correct to me and results in properly exported symbols. So it
should work correctly when using gold (from recent enough binutils version,
didn't try to bisect).
HJ, can you look to fix GNU ld?
