    Disable sntrup761 if compiler doesn't support VLAs.
    
    The sntrup761 code sourced from supercop uses variable length
    arrays.  Although widely supported, they are not part of the ANSI
    C89 spec so if the compiler does not support VLAs, disable the
    sntrup761x25519-sha512 at openssh.com KEX method by replacing the kex
    functions with no-op ones similar to what we do in kexecdh.c.
    
    This should allow OpenSSH to build with a plain C89 compiler again.
