  28 #   - KBUILD_TARGET, KBUILD_HOST, KBUILD_HOST_ARCH, and KBUILD_TYPE in the env.
  29 #   - KBUILD_PATH points to ./kBuild with an absolute path.
  30 #   - KBUILD_BIN_PATH and PATH_KBUILD_BIN must *NOT* be defined anywhere.
  31 #   - Current directory == bootstrap.gmk directory.
  32 #   - mkdir -p works.
  33 #   - ln -s works
  34 #   - cp -f works
  35 #   - cd somedir && command works.
  36 #   - echo done > some-file works.
  37 #   - Recent GNU make that implements CURDIR, $(error) and ifdef.
