The legacy support for the old BUILDROOT_DL_DIR and BUILDROOT_CONFIG breaks down when make is invoked recursively - which is done in a few cases, e.g. silentoldconfig, external-defs, ... These targets always give a legacy error. For BUILDROOT_DL_DIR, this is fixed by making sure that the original value of BR2_DL_DIR taken from the environment is also exported again. For BUILDROOT_CONFIG, this is fixed with an additional comparison of the environment variable's value with the fake value that we introduce ourselves.
