If we are going to hard code .init and .fini names (and we do that
elsewhere) I think it would be better to disable the sorting when
looking at the output_section_statement rather than the
wild_statement.

Hmm, even better, inplement a SORT_NONE script keyword to extend our
current list of sorting keywords, SORT_BY_NAME, SORT_BY_ALIGNMENT and
SORT_BY_INIT_PRIORITY.  SORT_NONE does the obvious, overriding
--sort-section=name and --sort-section=alignment.
