[ofa-general] Another XRC binary compatable issue for different pthread version.

[Tang, Changqing]

HI:
        Here is the ibv_srq structure:

struct ibv_srq {
        struct ibv_context     *context;
        void                   *srq_context;
        struct ibv_pd          *pd;
        uint32_t                handle;

        pthread_mutex_t         mutex;
        pthread_cond_t          cond;
        uint32_t                events_completed;

        uint32_t                xrc_srq_num;
        struct ibv_xrc_domain  *xrc_domain;
        struct ibv_cq          *xrc_cq;
};

On redhat 5 system, since it has a new pthread version, 'pthread_cond_t' is larger
than on redhat 4 system.

So if I compile the code on redhat 5 system, it won't run on redhat 4 system, and
vice versa.
