linux-user/signal.c: Remove only-ever-set variable fpu_save_addr
Move the access of fpu_save into the commented out skeleton code for restoring FPU registers on SPARC sigreturn, thus silencing a gcc 4.6 "variable set but never used" warning. (This doesn't affect the calculation of 'err' because in fact __get_user() can never fail.) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Riku Voipio <riku.voipio@iki.fi>
