Toolchain is not ready

I have problem with STM32duino core's toolchain. Arduino IDE can build STM32duino project, but Stino can't.

Paths for tools are:

C:\Users\silvi\AppData\Local\Arduino15\packages\STM32\tools\CMSIS\5.5.1-1.1
C:\Users\silvi\AppData\Local\Arduino15\packages\STM32\tools\STM32Tools\1.3.2\tools
C:\Users\silvi\AppData\Local\Arduino15\packages\STM32\tools\xpack-arm-none-eabi-gcc\9.2.1

Now, I found that function `check_platform_dep` get's wrong direction. Why?
Please, fix this bug! Thanks!
