[Buildroot] Autobuild reproduction and generation

[Yu-Ting, Kao]

Thank you for your reply.

I follow these steps at below:

1. wget command to get br-reproduce-build.
2. prepare a clean buildroot from git repo.
3. modify br-reproduce-build script. At line 6:

       BASE_GIT="${BASE_GIT:-/[MY_CLEAN_BUILDROOT_DIR_PATH]}"

4. Find the issue id that I want to reproduce. For example, "
http://autobuild.buildroot.org/results/358/358e2f02f42e08fe362ecd46e636c0048e77c21f/
<http://autobuild.buildroot.org/results/1d5/1d530863f727a097330be6bce29fe00e148bb587/>"'s
issue id is 358/358e2f02f42e08fe362ecd46e636c0048e77c21f

5. run "./br-reproduce-build 358/358e2f02f42e08fe362ecd46e636c0048e77c21f/"
6. The error log is (Cannot reach to the core of issue)
