Well, I just imported the patch from crosstool-ng without renaming it,
but I did run the build test for the 6 versions of gcc Buildroot
currently supports:
- 4.7.4 (deprecated): patch not needed
- 4.8.5: patch needed
- 4.9.3: patch needed
- 5.3.0: patch needed
- 6.1.0: patch needed
- arc-2015.12 (based on gcc-4.8.5): patch needed

If you prefer, I can rename them, then repost the patch...
