No. There are not practically enough cycles saved to overcome the often minutes of CPU time to build every update of a large software package.
> When every program is compiled for a specific architecture
Every binary distribution already "compiles" for a specific architecture.
The inane variant "tuning" generally renders miniscule speedups. Even if there is performance to be gained it can be done on a limited case by case basis.
