This is a minimalist use-case that still supports source-location based breakpoints, and identifying functions according to their ELF symbols.  It differs from a line-tables-only scenario because the latter still has a minimal .debug_info section to provide information about inlined functions.

For what it is worth, ld.bfd doesn't print source names in these testcases without this patch, so it is probably common to have at least a minimal .debug_info.
