toolchain: add a version that can be bumped to force toolchain/target rebuild 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 <nbd@nbd.name> 2021-11-17 04:46:21 +08:00			`#!/bin/sh`
check-toolchain-clean.sh: fix shellcheck warnings Fixes following complaints and suggestions: In scripts/check-toolchain-clean.sh line 2: eval `grep CONFIG_GCC_VERSION .config` ^-- SC2046 (warning): Quote this to prevent word splitting. ^-- SC2006 (style): Use $(...) notation instead of legacy backticks `...`.
