Oh, maybe an explanation: what is expected is that such decls (externs) either
have no context set (global) or have the current function as context.  For
inlining (cloning/versioning all the same) this needs to be done by remapping
the decls.  No idea why this isn't called on the _switch_mode_errorstr
in the inliner.  As this works with normal functions I assume that somehow
the free_lang_data work changed internal structures in a way that this decl
isn't visible to the inliner anymore (in a way).
