Similar to #31840, currently our Linux toolchain file contains: ```bash set(CMAKE_AR "aarch64-linux-gnu-ar") set(CMAKE_RANLIB "aarch64-linux-gnu-ranlib") set(CMAKE_STRIP "aarch64-linux-gnu-strip") set(CMAKE_OBJCOPY "aarch64-linux-gnu-objcopy") set(CMAKE_OBJDUMP "") ``` `objdump` is currently only used for the macOS cross build, where it's `llvm-objdump`, but we should be consistent in producing a toolchain file that points to actual tools, rather than leaving variables unset.
