--- Comment #1 from Mark Wielaard <m...@klomp.org> ---
The RISC-V Hardware Probing Interface is non-trivial
https://docs.kernel.org/arch/riscv/hwprobe.html
But at the moment we only have the basic RV64GC instruction set.
Which I believe is what glibc assumes if riscv_hwprobe isn't implemented.
So as a quick workaround we could just "implement" riscv_hwprobe as ENOSYS.
