On darwin, all virtual sections have zerofill type, and having a .zerofill directive in a non-virtual section is not allowed. Instead of asserting, show a nicer error. In order to use the equivalent of .zerofill in a non-virtual section, the usage of .zero of .space is required. This patch replaces the assert with an error.
