Remove -ffast-math from makefiles on armv8. This option causes the following error when building on the rpi5 (armv8.2a):
/usr/lib/gcc/arm-linux-gnueabihf/12/include/arm_neon.h: In function ‘float16x4_t vmul_n_f16(float16x4_t, float16_t)’:
/usr/lib/gcc/arm-linux-gnueabihf/12/include/arm_neon.h:17755:14: error: conversion of scalar ‘float’ to vector ‘float16x4_t’ involves truncation
This also disables it for other armv8 platforms (that didn't have this problem), but the option does come with some risks and was added to code which I don't think will benefit such as mupen64plus-ui-console.
