Can't link examples due to Acconeer libraries being built with GCC < 10.0

[nerwalt]

GCC 9.3.1 was used to build the Acconeer libraries. This specific version is from 2020, and GCC 9 went EOL in May 2022. The examples use the system arm-none-eabi-gcc, which I suspect is >= GCC 10.0 for most people. When running the examples, I get the following error: '...liba121_sys-0fb701def0e08057.rlib' generated with GCC compiler older than 10.0. The fix is to download a suitable version of GCC 9, such as 9.3.1 and set it as the linker in .cargo/cargo. toml in the examples.

iirc the BUILDINFO for the library built with gcc specifies the version they used (and require you to use basically)

Compiler version:
arm-none-eabi-gcc (GNU Arm Embedded Toolchain 9-2020-q2-update) 9.3.1 20200408 (release)
