New SDCC version

[ludiazv]

Some months ago SDCC team realeased a new version 3.9 that include serveral improvements for stm8 platform. Here are the release notes: https://sourceforge.net/p/sdcc/news/2019/04/small-device-c-compiler-390-released/

Pio now uses 3.8 version. I think it could be a good idea to update the platform with this new version.

Regerds,

Update: There's now SDCC v4.0 and it even reduces firmware sizes in the SPL and Blinky firmwares :)

Also some users reported that it doesn't work without the SDCC v4.0 toolchain (https://community.platformio.org/t/error-309-arduino-fade-all-pins-for-the-platform-st-stm8/13690/20?u=maxgerhardt).

AFAIK the 4.1 release is already in release candidate status. Maybe you should wait a few more days...
