Sönke Holz dfce2f6341 Kernel/riscv64: Explicitly discard temporary local symbols
This is for some reason needed for riscv64 clang, as otherwise the
kernel.map file would grow too big to fit in its section inside the
kernel image.
None of our other architectures have temporary locals in their
kernel.map.
