Pull Request Overview

This PR adds a workaround for a patchelf.rb bug that affects the rqlite formula on Linux ARM64 systems when CGO is required for go-sqlite3. The workaround ensures proper build configuration by explicitly enabling CGO and configuring the linker to use PIE (Position Independent Executable) mode.

Key Changes:

• Added platform-specific build configuration for Linux ARM64
• Explicitly enabled CGO and external linking
• Configured Go to build in PIE mode to prevent patchelf corruption
