stdlib/tst-setcontext.c: Check for clobbering of signal stack
On aarch64 calling swapcontext clobbers the state of the signal stack (BZ #16629). Check that the address and size of the signal stack before and after the call to swapcontext remains the same. ChangeLog: 2014-04-17 Will Newton <will.newton@linaro.org> [BZ #16629] * stdlib/tst-setcontext.c: Include signal.h. (main): Check that the signal stack before and after swapcontext is the same.
