-pipe no longer used by default

Meson used to add the -pipe command line argument to all compilers that supported it, but no longer does. If you need this, then you can add it manually. However note that you should not do this unless you have actually measured that it provides performance improvements. In our tests we could not find a case where adding -pipe made compilation faster and using -pipe can cause sporadic build failures in certain cases.
