commit d934006a4ac40946fea9ee97fed5f21990ff5228

Chopstx is an RT thread library for STM32F103 and GD32F103 (ARM Cortex-M3), STM32F030 (ARM Cortex-M0), MKL27Z (ARM Cortex-M0plus), STM32L432 (ARM Cortex-M4), GD32VF103 (RISC-V Bumblebee) and emulation on GNU/Linux.

In 2.5, we added GD32VF103 support. Please note that default libc is now picolibc (instead of newlib).
