Actually, crx is not the only target with this problem:

Is that really printing -Werror=edantic or a problem copy+pasting?

Yes, it's really printing that.
I think that that's because gcc thinks -pedantic starts with -W...
in opts.c:option_name we have:
/* A warning classified as an error. */
if ((orig_diag_kind == DK_WARNING || orig_diag_kind == DK_PEDWARN)
&& diag_kind == DK_ERROR)
return concat (cl_options[OPT_Werror_].opt_text,
/* Skip over "-W". */
cl_options[option_index].opt_text + 2,
NULL);

I know, I wrote that code but missed the -pedantic case. I opened PR 44774

--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=21088&action=view)
patch which needs testing
I have not tested this fix but it should work and should remove the
warning/error for these targets.

No, the translation unit is still considered empty.
You have to put something syntactic into it, although it could be an
extern declaration, an static inline function, or a struct declaration, e.g.:
struct rtx_def;
