Having 7 of your 8 cores sitting in their idle loop is probably your
#1 thing to address. . . .

With a very large selection of packages, perhaps you could split them
into several (8, 9?) Buildroot trees.
Then run those buildroot instances as jobs at the same time.

Or...

At least pull the really big time consumers out, into their own BR
instance, and use your idle cores on those.
