* Make usage of top-level make easier, drop 'all' target Make it easier when using top-level make - proxy all possible commands to Buildroot make and only wrap build for individual target builds. This way it's still possible to run e.g. 'make ova' which would read the defconfig and run the build, while we can also use the top-level make in the same way as it's in vanilla Buildroot. Target 'all' was dropped in favor of Buildroot 'make' without any arguments - as it's fairly pointless to run all builds sequentially. With the current 19 targets it would take about a day even on a decent hardware and the build artifacts would be lost in the process. * Show warning only if BR2_DEFCONFIG changes * Wait for 10s or input if defconfig differs
