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.
