MakePROOFPackage does not create the packages directory when updating

[nsjarvis]

I ran into this when updating a (fairly recent) installation. I did not encounter it previously when making a new build elsewhere.
It was easily fixed by 'mkdir Linux_CentOS8-x86_64-gcc8.5.0/packages' and running make again.
