    Work around IA64 tst-setcontext2.c compile failure.
    
    Building tests for IA64 runs into a build failure compiling
    stdlib/tst-setcontext2.c:
    
    tst-setcontext2.c: In function 'do_test':
    tst-setcontext2.c:210:20: error: passing argument 1 of 'sigismember' from incompatible pointer type [-Werror=incompatible-pointer-types]
       if (sigismember (&oldctx.uc_sigmask, SIGUSR2) != 1)
                        ^
    
    Indeed, the IA64 uc_sigmask as unsigned long rather than the larger
    userspace sigset_t.  Fixing this might be hard; this patch works
    around the build failure by making IA64 wrap the test with a version
    that #defines sigismember to add a cast (I'd welcome a better approach
    for fixing this).
    
    Tested (compilation only) for ia64.
