See ldlang.c:lang_check. Quite illogically, incompatible arches
(as signalled by this function) are only *warned* about, while with
this function signalling compatible ones, we can have the
cris_elf_merge_private_bfd_data function return an error. This is
undoubtedly a FIXME: in general. Also, the
command_line.warn_mismatch flag and the --no-warn-mismatch option
are misnamed for the multitude of ports that signal compatibility:
it is there an error, not a warning. We work around it by
pretending matching machs here. */
