This breaks building ARC platforms, and possibly others.  Note that
tools/buildman/buildman is happy to fetch toolchains for you, and in
this case it's also just the current kernel.org cross-toolchain. Please
see https://docs.u-boot.org/en/latest/develop/ci_testing.html about how
to trigger a CI run prior to sending v4, thanks.
