We currently create HOST_DIR, TARGET_DIR, STAGING_DIR and BINARIES_DIR in their respective installation steps. However, as we are about to change how the logic to capture files installed by packages is implemented, we will need these directories to exist at the configure step to keep things simple. Note that when BR2_PER_PACKAGE_DIRECTORIES=y, the HOST_DIR, TARGET_DIR and STAGING_DIR are anyway already created at the configure step, when populating the per-package HOST_DIR and TARGET_DIR. This also means that we can drop the "mkdir" from per-package-rsync.
