Thanks. On my side I have been busy on other things, so I haven't
touched at GnuK at all. I still plan to work on adding support for
STM32L432 in the future though.

About the change my goal in putting it in mcu/sys-*.h was to be able to
use the same implementation for different microcontrollers. The
STM32F103 and STM32L432 share the same USB IP, but the STM32F103 has
it mapped to IRQ 20, while the STM32L432 has it mapped ot IRQ 67. Maybe
the best for that would be to put it instead in mcu/stm32f103.h and
mcu/stm32l432.h? I am personally not a big fan of too many #ifdef
#endif.
