    Fix dlfcn/failtestmod.c warning.
    
    This patch fixes a "set but not used" warning from
    dlfcn/failtestmod.c.  A variable is used only to store the return
    value from dlsym.  As I understand this test, the point is simply to
    do a sequence of load / unload operations in a loop, and all that
    matters here is that dlsym gets called and returns without crashing,
    not what its return value is.  So this patch removes the assignment to
    a variable.
    
    Tested for x86_64.
    
            * dlfcn/failtestmod.c (constr): Do not store result of dlsym in a
            variable.
