[WIP] @eunomia-bpf/bpf-developer-tutorial/issues/148 can you check it?

[Copilot]

• Analyzed issue [BUG] Failed to build blazesym #148: blazesym build failure on aarch64 Ubuntu 20.04
• Identified root cause: linker script too aggressively discards sections including .got.plt
• Investigated existing workarounds and features in blazesym
• Fixed linker script to avoid discarding essential sections on aarch64
• Improved build.rs error handling to provide better warnings
• Tested workaround with dont-generate-test-files feature
• Created comprehensive documentation with multiple workaround options
• Updated main README to reference workaround documentation
• Verified that tutorial examples already use the workaround correctly

Summary

The issue has been thoroughly analyzed and documented. The repository already contains working examples that use the dont-generate-test-files feature flag to work around the ARM64 linker issue. The solution provides:

1. Immediate workaround: Use cargo build --features=cheader,dont-generate-test-files
2. Working examples: All blazesym-using examples in the repo already implement this
3. Comprehensive documentation: Detailed guide for users encountering this issue
4. Multiple options: Several alternative solutions depending on use case

The core functionality of blazesym and the tutorial examples remain fully functional on ARM64 platforms.
