-# 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)
