Comment:
I'm a bit confused how to best create the patch fie in `-Np1` format. 
I tried it with `diff -Naurp0` but now the patch cannot be applied (I tested locally 
with the wrong `./xbps-src` cmd,  hence the failing check :man_facepalming:) 

What is the recommended way of creating such patch files? `git diff`?
