2022-11-29Fix non-Linux buildsSamuel Thibault
Various tools are Linuxish and should thus only attempted to build on Linux only. Some features are also Linux-only. Also, libresolv is used on all GNU platforms, notably GNU/Hurd and GNU/kfreeBSD.

2021-04-13watchdog: make open-write-close-open functionality a config knobRasmus Villemoes
The behaviour introduced by commit 31c765081dc4 ("watchdog: stop watchdog first on startup") causes warnings in the kernel log when the nowayout feature is enabled: [ 16.212184] watchdog: watchdog0: nowayout prevents watchdog being stopped! [ 16.212196] watchdog: watchdog0: watchdog did not stop! The latter may also appear by itself in case the watchdog is of the type that cannot be stopped once started (e.g. the common always-running gpio_wdt kind). These warnings can be somewhat ominous and distracting, so allow configuring whether to use this open-write-close-open sequence rather than just open. Also saves a bit of .text when disabled: function old new delta shutdown_on_signal 31 58 +27 watchdog_main 339 306 -33 shutdown_watchdog 34 - -34 ------------------------------------------------------------------------------ (add/remove: 0/1 grow/shrink: 1/1 up/down: 27/-67) Total: -40 bytes Make it default n: - It's a workaround for one specific type of watchdog (and that seems to be a defect in the kernel driver) - Even when not enabled in busybox config, it can easily be implemented outside busybox - Code size - Commit 31c765081dc4 should be considered a regression for all the boards that now end up with KERN_CRIT warnings in dmesg. - The author of that commit said "This use case is evidently rare, so if it is indeed causing problems for other people I'd OK then I understand whatever needs to be done." in the v1 thread.
