Compile the program for ARM64

[HaroleDev]

I was trying to install pantheon-tweaks through the PPA only to realize that it is only compiled for AMD64. While it is nice that I can compile myself, wouldn't it be nice to get that compiled straight to the PPA?

The source code itself doesn't depend on architectures, the only thing we need to do is to set up the PPA for ARM64, but unfortunately I have no permission to do that.

@Philip-Scott Could you set up your PPA of pantheon-tweaks ready for ARM64 with the following steps?

1. Log in to Launchpad
2. Open https://code.launchpad.net/~philip.scott/+recipe/pantheon-tweaks-git and click "Change details" from the right menu
   
3. Under "Processors:" section, check the "ARM ARMv8 (arm64)" checkbox like the following screenshot

Done! Let me know if this doesn't do the trick :) My guess is that the next commit should have the ARM build

It seems to be available now. Thank you for setting PPA up @Philip-Scott and reporting issue @HaroleDev!
