[Qemu-devel] [PATCH v5 02/19] tcg/sparc: Use the proper compilation flags for 32-bit |

We have required a v9 cpu since 9b9c37c36439ee0452632253dac7a31897f27f70.
However, the flags we were using did not reliably enable v8plus, which
meant that the compiler didn't know it could inline 64-bit atomics.
