27# ASSUMES:
[1506]28# - KBUILD_TARGET, KBUILD_HOST, KBUILD_HOST_ARCH, and KBUILD_TYPE in the env.
[1529]29# - KBUILD_PATH points to ./kBuild with an absolute path.
30# - KBUILD_BIN_PATH and PATH_KBUILD_BIN must *NOT* be defined anywhere.
[995]31# - Current directory == bootstrap.gmk directory.
32# - mkdir -p works.
33# - ln -s works
34# - cp -f works
35# - cd somedir && command works.
[1506]36# - echo done > some-file works.
[1529]37# - Recent GNU make that implements CURDIR, $(error) and ifdef.
