CONFIG_LLD_VERSION was originally added in commit d5750cd3c548 ("kbuild: Disable CONFIG_LD_ORPHAN_WARN for ld.lld 10.0.1"), which is not applicable to 4.19. Additionally, lld-version.sh was eliminated and combined into ld-version.sh in commit 02aff8592204 ("kbuild: check the minimum linker version in Kconfig") and there was a follow up fix in commit 1f09af062556 ("kbuild: Fix ld-version.sh script if LLD was built with LLD_VENDOR"), which is a little large to take into android-4.19-stable for the sake of fixing an LTO issue. Add scripts/lld-version.sh but based on the upstream version of ld-version.sh so that we benefit from the fixes but do not have to backport a ton of patches just to get access to CONFIG_LLD_VERSION.
