RFR: 8301197: Make sure use of printf is correct and actually needed

[Magnus Ihse Bursie]

We have been sloppy in our use of `printf` in make code. Most of the time, we should really use `echo` instead. If we do need to use `printf`, we should never inline make or shell variables into the formatting string, since they may contain `%` which will be interpreted as formatting. Instead, we should always use `%s` and pass the variable as an argument to `printf`.

I've checked the entire code base for usages of $PRINTF, and converted most of them to $ECHO, and made sure the remaining ones are correct. I also discovered some additional ugly stuff in relation to this, which I fixed.
