linux-user/include/host/sparc64: Fix host_sigcontext
Sparc64 is unique on linux in *not* passing ucontext_t as the third argument to a SA_SIGINFO handler. It passes the old struct sigcontext instead. Set both pc and npc in host_signal_set_pc. Fixes: 8b5bd461935b ("linux-user/host/sparc: Populate host_signal.h") Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
