Script to copy recursively {config.make,Makefile} to each example folder

[dimitre]

I'm using this to help testing RPI4 maybe it can be interesting to have it on repository not sure about the file name

[artificiel]

just to understand well: this is a more "adaptive/generic" version of the "update multiple" of PG (in the sense that it does not take a specific template?)

This is a script I'm using to quickly compile using make in some freshly installed OF without having to compile PG. make build is really similar in all linux flavors, so I got all examples compilable in no time
