  Log Message:
  -----------
  Fix a case where multiple symbols with zero size would cause duplicate entries in gsym files.

Symbol tables can have symbols with no size in mach-o files that were failing to get combined into a single entry. This resulted in many duplicate entries for the same address and made gsym files larger.
