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.
