Newer arm-none-eabi-gcc and STDIO_FLOATING_POINT

Hello,

up to gcc-arm-none-eabi-9-2019-q4-major, compiling some configuration
defining  STDIO_FLOATING_POINT succeeded.  With
gcc-arm-none-eabi-9-2020-q2-update and later, at least fflush has
multiple definitions and _exit, _kill and friends are undefined
references.

Errors vary with the different combinations of --specs=nosys.spec and
----specs=nano.specs, but I no find a real solution.

Do you have the problem too? Any hints to solve?

Thanks
