The archive that I get with this recipe has a different hash and contents
than the 1.9.0 tarball on the libssh2 website:
http://www.libssh2.org/download/libssh2-1.9.0.tar.gz

The one from the libssh2 website has LIBSSH2_VERSION set to “1.9.0”.  The
one from git hub says “1.9.0_DEV”. (Amongst other differences.)
