oe/copy_buildsystem.py: dereference symlinkrbt/cp
When there is a relative symlink in the layer, for example: symA -> ../out/of/layer/file symA will be invalid fater copied, it would be invalid from build time if it points to a relative path, and would be invalid after extracted the sdk if it points to a absolute py. Dereference symlink when copy will fix the problem. Use tar rather than shutil.copytree() to copy is because: 1) shutil.copytree(symlinks=Fasle) has bugs when dereference symlinks: https://bugs.python.org/issue21697 And Ubunutu 1404 doesn't upgrade python3 to fix the problem. 2) shutil.copytree(symlinks=False) raises errors when there is a invalid symlink, and tar just prints a warning, tar is preferred here since the real world is unpredicatable 3) tar is faster than shutil.copytree() as said by oe.path.copytree() So use tar to copy.
