Server: Fix bug with --interface flag when "cc" is not installed.
* mandos (IPv6_TCPServer.server_bind): Since we fall back to setting
SO_BINDTODEVICE to a hard-coded value if we failed to find out what
it is, declare it as global so Python does not think that we are
creating a new local variable.
* mandos (IPv6_TCPServer.server_bind): Since we fall back to setting
SO_BINDTODEVICE to a hard-coded value if we failed to find out what
it is, declare it as global so Python does not think that we are
creating a new local variable.
