Subject: [PATCH] qemu/mcu/arm/stm32.ld: Fix C++ linking.

This commit expands the linkerscript for STM32-series boards to let C++
code link with the interpreter core.

The linkerscript now contains all necessary sections for C++ code that
uses exceptions to be part of a user module inside the MicroPython
image.
