[Rd] La_library() always returns "" on R-devel?

[Gábor Csárdi]

Seems like this in 83986 [1] needs a fix in Lapack.c:

        if (dladdr((void *) F77_NAME(ilaver), &dl_info)) {
            char buf[PATH_MAX+1];
            char *res = realpath(dl_info.dli_fname, buf);
            if (res) {
                SEXP nfo = R_NilValue;
                if (strstr(res, "flexiblas"))
                    nfo = R_flexiblas_info();
                if (isNull(nfo))
                    nfo = mkChar("");
                ans = ScalarString(nfo);
                break;
            }
        }

It will always return an empty string except for flexiblas. I assume
this is not intentional.
