x86/build: Keep local relocations with ld.lld [ Upstream commit 7c21383f3429dd70da39c0c7f1efa12377a47ab6 ] The LLVM linker (ld.lld) defaults to removing local relocations, which causes KASLR boot failures. ld.bfd and ld.gold already handle this correctly. This adds the explicit instruction "--discard-none" during the link phase. There is no change in output for ld.bfd and ld.gold, but ld.lld now produces an image with all the needed relocations.
