The upgrade instructions say that after upgrading gcc (I went from 5.4.0 to 7.3.1):
"For upgrading to 1.2, you have to rebuild all packages, which will ensure that your system is fully optimized with the new gcc."
Before I do this, I want to make sure it is really necessary. I did not change my subarch (something which was covered in those upgrade instructions). I am staying with "generic_64". So do I still need to rebuild all the packages on my system?
