On riscv, kernel modules end up with a significant number of local symbols. This becomes apparent when compiling modules with debug symbols enabled. Using amdgpu.ko as an example of a large module, on riscv the size is 754MB (no stripping), 53MB (--strip-debug), and 21MB (--strip-unneeded). ON x86, amdgpu.ko is 482MB (no stripping), 21MB (--strip-debug), and 20MB (--strip-unneeded). Use --strip-unneeded instead of --strip-debug to strip modules so decrease the size of the resulting modules. This is particularly relevant for riscv, but also marginally aids other architectures.
