    As of a29dc8fd (2019-04-26), golang.org/x/crypto requires math/bits.
    math/bits was introduced in Go 1.9, so we can no longer build from head
    using 1.7.
    Building using Debian's packaged dependencies should work just fine, but
    since we want Travis to build from head, this commit updates the minimum
    supported version to 1.9.
