The freestanding CI builds were failing during CMake's initial compiler test because the -ffreestanding flag was causing linker issues. The linker expected a main() function but freestanding environments may not have one. This fix sets CMAKE_TRY_COMPILE_TARGET_TYPE=STATIC_LIBRARY when freestanding mode is enabled, which instructs CMake to skip the linking step during compiler tests and only compile to static libraries. This resolves the undefined reference to main error in CI while maintaining proper freestanding compilation semantics. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

Nice! There is a bug in CMake and I hope that they will fix it. But in the meantime, changing the target type will resolve our CI issues. I wasn't aware of this issue.
