[Rd] core dump on 64-bit Solaris (PR#990)

[tlumley@u.washington.edu]

Using the 64-bit Solaris compilers make check dumps core in La_rs at
   73       F77_CALL(dsyev)(jobv, uplo, &n, rx, &n, rvalues, work, &lwork,
&info);

I can't reproduce it easily, but example(eigen) occasionally stops with
  Error: abs(sm - V %*% diag(lam) %*% t(V)) < 60 * Meps is not TRUE
which might be connected. The tiny rounding errors in example(eigen)
aren't constant from time to time, but I don't know if they should be.
