    Merge commit 7a66a26658f4 from llvm git (by Fangrui Song):

      --discard-locals/--discard-all: allow and keep symbols referenced by
relocations

      In GNU objcopy, symbols referenced by relocations are retained. Our
      COFF (https://reviews.llvm.org/D56480) and Mach-O
      (https://reviews.llvm.org/D75104) ports port the behavior, but the ELF
      port doesn't.

      This PR implements the behavior for ELF.
      Close #47468 (tcl has a use case that requires `strip -x tclStubLib.o`
      to strip local symbols not referenced by relocations.)
