Can not use stm32f3xx-hal, fails in flip-link.

[StephenVanWijk]

The moment I comment out in Cargo.toml the stm32f3xx-hal reference, it builds without errors, without warnings.
But including the crate stm32f3xx-hal give a lot of complaints from flip-link.
I have checked my Rust embedded VCS setup, and will continue to do so, so far, everythings seems to function okay.
To check extra, I going to program STM32F303 via STMcubeProgrammer. I don't expect that the board is the problem, but just to make sure.
I thought, well, I try it via the crate stm32f3, then I can reach the registers directly. But that crate gives similar results.

• **Chip: stm32f303xc
• Rust version: 1.88.0
• flip-link version: 0.1.10
