Clean up the -make examples/-no-make examples/-compile-examples confusion

Currently there are two ways that appear to ensure you can build the examples when you configure, this being -make examples and -compile-examples. Currently if you don't specify anything it defaults to not making the examples which is not clear from the configure help at all.

In addition, it seems that doing -make examples also has no effect, and -compile-examples needs to be used instead. Can this please be cleaned up as right now it's confusing as to what needs to be done just to get the examples in a state that can actually be compiled at some point later on down the line. I would expect that -compile-examples is on by default and it should be turned off if this is not required.
