Subject: [PATCH] configure: loongson revert expensive optimizations in gcc O3
 optimization


The failure of fate-acodec-dca or dca2 tests are caused by ccache.
At the same time enable ccache and expensive-optimizations, dca parser
would be compiled incorrectly. So there is no bug in loongson gcc-4.9.x.
