The missing symbols are created by a linker script. So I guess the
important thing is the linker version.

My tools are

riscv64-linux-gnu-gcc (Debian 10.2.1-6) 10.2.1 20210110
GNU ld (GNU Binutils for Debian) 2.35.2

on an *aarch64* Debian Bullseye system.

I am on commit a731c7e36988c33.

On an amd64 system with the same software release I am not able to
reproduce the problem.

Best regards

Heinrich
