fix: replace bash syntax with sh in configure-v3

[bombermine3]

Overview

Since sh is the default shell in the Makefile, running configure-v3 resulted in the error: /bin/sh: 2: [[: not found. This fix modifies the syntax to be compatible with sh, allowing the script to run successfully without errors.

📝 Walkthrough

Walkthrough

The pull request modifies the Makefile, specifically the configure-v3 target. It changes the string comparison operator from == to = for determining the operating system, ensuring consistent behavior across macOS and other systems. The existing logic for modifying the configuration file remains unchanged, and a minor formatting adjustment is made by removing an unnecessary newline. Overall, the structure and functionality of the Makefile are preserved.

There are 3 ways to chat with CodeRabbit:

‼️ IMPORTANT
Auto-reply has been disabled for this repository in the CodeRabbit settings. The CodeRabbit bot will not respond to your replies unless it is explicitly tagged.

• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Line range hint 308-316: LGTM! Shell compatibility fix looks good.

The changes correctly use POSIX sh compatible syntax for string comparison (= instead of ==), which resolves the /bin/sh: 2: [[: not found error. The functionality remains unchanged while ensuring better shell compatibility.
