def objects
  # This partitions the list into .o's first and .a's last. This
  # is because gcc on some platforms require that static libraries
  # be linked last. This is because gcc builds a list of undefined
  # symbols, and then when it hits a .a, looks in the archive
  # to try and resolve those symbols. So if a .o needs something
  # from a .a, the .a MUST come after the .o
