Huh, 131072 .debug_types sections with different group signatures.  Yes, that
will take a while to process in obj_elf_change_section.  We can look up a
section by name fairly quickly via the section hash table to see whether
assembly should append to an existing section, but there is no quick lookup of
sections matching a group signature.
