    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.
