Since C99, `FLT_EVAL_METHOD` should be left for the compiler/libc to define. Its redefinition breaks compilation with picolibc as the target's libc, since it defines said symbol in math.h before the libm define is evaluated by the compiler. In its place, there is a check to make sure floating point type sizes are what are expected to be, triggering a compilation error if those assumptions are no longer valid.
