I believe that your CFLAGS/LDFLAGS analysis for this warning (as well as
the proposed change) is correct.

There is more than one possible reason for this: The C compiler may not
have not added debug symbols in the first place (look for -g...). Or the
debug symbols may have been removed afterwards (look for strip or
install -s).
