This board benefits from Link Time Optimisations due to the limited flash storage, however the default V9.2.1 toolchain from 2019 does not compile a binary that is able to run on the STM32G0B1CBT MCU used on this board. Updating the a later version of the gccarmnoneeabi toolchain (V10 or higher) works for all attempts at compiling and running marlin on the STM32G0B1CBT

Description
This board benefits from Link Time Optimization due to the limited flash storage, however the default V9.2.1 toolchain from 2019 does not compile a binary that is able to run on the STM32G0B1CBT MCU used on this board. Updating the a later version of the gccarmnoneeabi toolchain (V10 or higher) works for all attempts at compiling and running marlin on the STM32G0B1CBT.
Without this fix the compiled binary does not start to run on the MCU, even though it throws no compile errors.
Requirements
Big Tree Tech EBB42(or 36) V1.1 or V1.2 using a STM32G0B1CBT MCU
Benefits
Reduces the flash usage for a space constrained MCU allowing for more Marlin features to be compiled in whilst keeping features such as the splash screen with minimal issue, and also using the last page of flash for a virtual EEPROM. Its still scraping 98.4% memory usage after this, but wouldn't even fit without LTO.
