This leads to different object file output when cross-compiling to i386, or native. Similar to 7af3432e22b0, we need to add a `volatile` qualifier to the local `Weight` variable to force it onto the stack, and avoid the exc= ess precision. Define `stack_float_t` in `MathExtras.h` for this purpose, and use it. This is the version of the fix for PR276961 that landed upstream.
