Review Comment:
> Why we rely on `ARCH_FPU`? The `LIBC_FLOATINGPOINT` does not have anything
about hard vs soft FPU. Or for archs with `ARCH_FPU` the code size increase is
low?
I assume that it's rare to use float point if the hardware doesn't support
FPU directly. So, LIBC_FLOATINGPOINT is disabled by default in this case, but
user can enable it if they really want to.
