It turned out that Landlock Make hasn't been applying sandboxing for a while, due to a mistyped if statement for `$(USE_SYSTEM_TOOLCHAIN)` it should have had the opposite meaning. Regressions in the build configs have been fixed. The rmrf() function works better now. The rm.com tool works according to POSIX with the exception of supporting prompts.
