Simple inclusion of <chrono> leads to compilation error

[aentinger]

• Minimal sketch to reproduce the error:

  
  #include <chrono>

void setup() {

}

void loop() {

}

* Compile the sketch via `arduino-cli compile -b arduino:renesas_portenta:portenta_c33 -v .`.
* Error
```bash

Workaround:

-#include <chrono>
+#undef abs
+#include <chrono>

That patch was inherited by https://github.com/arduino/ArduinoCore-mbed/commit/2042db15a90339714f0654416f26c6e389c71aba , which unfortunately doesn't link the underlying issue :disappointed:

I wish it was fixed, it's driving me crazy. Worst part is it's not even my code crashing the build:
