# REQUIRES: standalone_build
# REQUIRES: OS=macosx

# As a result of incremental changes,
# in dry-run mode the symbol extraction
# still runs some real commands against the installation
# and symbol directories (e.g. find and cpio)
# This test explicitly checks that such commands
# do not cause build-script to fail when run
# against empty directories (which is the typical
# scenario in dry-run)
