I'm trying, but I can't figure out how to pass the needed --hash-style=gnu
option to the linker :-/

Thanks for the link, but I'm afraid it won't help here. The binutils version
is only important when you want to generate ELF files using the new .gnu.hash
section; it is of no use when you want to check if a particular system can
_run_ them.
