This addresses CVE-2015-8618 (a vulnerability in math/big)
This issue can affect RSA computations in crypto/rsa, which is used by
crypto/tls. TLS servers on 32-bit systems could plausibly leak their RSA
private key due to this issue. Other protocol implementations that
create many RSA signatures could also be impacted in the same way.
