# Subtle: We do not let the shell expand $(CORELIB_DSYM_GLOB) directly rather
# we use Make's $$(wildcard) facility. The reason is that, on mac, when using
# USE_SNAPSHOT_CORELIB, we copy the core.dylib file out of the snapshot.
# In that case, there is no .dSYM file. Annoyingly, bash then refuses to expand
# glob, and cp reports an error because libcore-*.dylib.dsym does not exist.
# Make instead expands the glob to nothing, which gives us the correct behavior.
# (Copy .dsym file if it exists, but do nothing otherwise)
