This makes the output ELF friendlier to llvm-objcopy, which otherwise complains about discarding .dynsym when it's (potentially) referenced by .rel.dyn.
Since u-boot doesn't actually make use of a dynamic linker, and these sections are only here because we're building --pie, it's best to discard what we don't need.
