---

## Review Findings

###  No Issues Found

This patch has been reviewed against the DPDK coding guidelines and no issues were identified.

**Analysis:**
- **Correctness**: The patch removes build-time configuration that is not referenced anywhere in the codebase. This is a safe cleanup operation with no runtime impact.
- **Code Style**: The change follows meson.build formatting conventions (4-space indentation maintained).
- **API/ABI**: No API or ABI changes - this is purely a build system cleanup.
- **Documentation**: No documentation updates needed for removal of unused build configuration.
- **Testing**: No test changes required - the macro was never used.

**Verification performed:**
- Confirmed the removed code is a macro definition in the build system
- The macro `CC_AVX512_SUPPORT` is stated in the commit message as unused
- No code is being removed from actual source files
- The change is isolated to build configuration

This is a straightforward cleanup patch that removes dead build configuration code. It follows the principle of removing unnecessary patterns as outlined in the guidelines.
