Disabling threads with native gcc-11/-12 produces a compiler error

Reproduce the command from the issue using build/cross/arm.txt and build/cross/cortex-m3.txt with -Denable-threading=false, then inspect the complete compiler error after the reported Meson warning. Compare the configuration with the README example and determine what change is needed for an official arm-none-eabi toolchain; done means the example builds successfully with threads disabled.

Running the build specified in the ci file (or an example given in the readme) with an official arm-none-eabi toolchain fails to compile.

• Project Version/Tag/Commit: 3d809a75669f3f3600a57ac2ab30f71591338bfb
• Operating System: Fedora 36
• SDK version: ?
• Toolchain version: See log; tried with two later releases with same effect

I set the path to the compiler by editing build/cross/arm.txt

I can imagine that there are some requirements on how the compiler itself is compiled (in that case having threads enabled?). Could you provide a working example with an official arm-none-eabi-gcc or point to a compiler that works with the example configuration of this project?

Thanks!
