The change is in the fn Perl_utf8n_to_uvuni :
-------------------
.....
....

#define UTF8_WARN_LONG                           8
#define UTF8_WARN_FFFF                           9 /*
Also FFFE. */

    if (curlen == 0 &&
        !(flags & UTF8_ALLOW_EMPTY)) {
        warning = UTF8_WARN_EMPTY;
        goto malformed;
    }
#ifdef EBCDIC   /* the change */
      uv = NATIVE_TO_UTF(uv);
#endif          /* the change ends here */

    if (UTF8_IS_INVARIANT(uv)) {
        if (retlen)
            *retlen = 1;
        return (UV) (NATIVE_TO_UTF(*s));
    }
....

I have other changes in utf8.c, but the build happens
fine with them (and without the change mentioned
above).

It doesnt fail.
