check-toolchain-clean.sh: workaround stray rebuilds

2022-02-28T14:17:11Z

It seems, that there are currently some unhandled corner cases in which `.toolchain_build_ver` results in empty file and thus forcing rebuilds, even if the toolchain was build correctly just a few moments ago. Until proper fix is found, workaround that by checking for this corner case and simply populate `.toolchain_build_ver` file. While at it, improve the UX and display version mismatch, so it's more clear what has forced the rebuild: "Toolchain build version changed (11.2.0-1 != ), running make targetclean" References: https://gitlab.com/ynezz/openwrt/-/jobs/2133332533/raw Signed-off-by: Petr Štetiar

toolchain: add a version that can be bumped to force toolchain/target rebuild

2021-11-16T21:02:45Z

This can be used to ensure that the compiled code is up to date, when something important changes in the toolchain. A recent example of this is the gcc 11 fix for a code miscompilation issue Signed-off-by: Felix Fietkau
