On riscv, GNU toolchain generated ~800MB+ of local symbols in .ko
files on riscv. When stripping .ko on riscv, discard these local
symbols by default to make .ko module sizes comparable to other
architectures.

This patch is tested on SiFive Unmatched and is shipped in
Ubuntu. This can be revisited once improved GNU toolchain becomes
available and is used.
