    configure.ac: properly set seccomp_audit_arch for MIPS64
    
    Currently seccomp_audit_arch is set to AUDIT_ARCH_MIPS64 or
    AUDIT_ARCH_MIPSEL64 (depending on the endinness) when openssh is built
    for MIPS64. However, that's only valid for n64 ABI. The right macros for
    n32 ABI defined in seccomp.h are AUDIT_ARCH_MIPS64N32 and
    AUDIT_ARCH_MIPSEL64N32, for big and little endian respectively.
    
    Because of that an sshd built for MIPS64 n32 rejects connection attempts
    and the output of strace reveals that the problem is related to seccomp
    audit:
    
    [pid   194] prctl(PR_SET_SECCOMP, SECCOMP_MODE_FILTER, {len=57,
    filter=0x555d5da0}) = 0
    [pid   194] write(7, "\0\0\0]\0\0\0\5\0\0\0Ulist_hostkey_types: "..., 97) = ?
    [pid   193] <... poll resumed> )        = 2 ([{fd=5, revents=POLLIN|POLLHUP},
    {fd=6, revents=POLLHUP}])
    [pid   194] +++ killed by SIGSYS +++
    
    This patch fixes that problem by setting the right value to
    seccomp_audit_arch taking into account the MIPS64 ABI.
