Hello Nilesh!Thank you for noticing this.Please add entries to debian/changelog in the future. I use `dch 'changed a thing'` followed by `debcommit -a` instead of using `git commit`, to ensure I document my changes.In your patch you removed `-O3`, I've put that back to simplify the patch. It doesn't hurt to specify that twice.
I've pushed my cleanups. Can you also add logic to compile rna-star multiple times using -mavx2 on down for amd64 along with a wrapper script?
