Aurelien Jarno 9aa5c222b9 sparc32: Add nop before __startcontext to stop unwinding [BZ #22919] ... On sparc32 tst-makecontext fails, as backtrace called within a context created by makecontext to yield infinite backtrace. Fix that the same way than nios2 by adding a nop just before __startcontext. This is needed as otherwise FDE lookup just repeatedly finds __setcontext's FDE in an infinite loop, due to the convention of using 'address - 1' for FDE lookup.
