However, the code is always changing; generated files are often moved to another directory, or removed when they become unnecessary. Such garbage files tend to be left over in the source tree because people usually git-pull without cleaning the tree. This is not only the noise for 'git status', but also a build issue in some cases. One solution is to remove a stale file like commit 223c24a7dba9 ("kbuild: Automatically remove stale file") did. Such workaround should be removed after a while, but we forget about that if we scatter the workaround code in random places. So, this commit adds a new script to collect cleanings of stale files. As a start point, move the code in arch/arm/boot/compressed/Makefile into this script.

LC_ALL, if set, overrides all other LC_* variables. LANG < LC_CTYPE, LC_COLLATE, LC_MONETARY, LC_NUMERIC, ... < LC_ALL This is why documentation such as [1] suggests to set LC_ALL in build scripts to get the deterministic result. LANG=C is not strong enough to override LC_* that may be set by end users.

A good thing is the variable name 'cross_compiling' is self-documenting. This is a simple replacement for m68k, mips, sh, for which $(ARCH) and $(SRCARCH) always match. No functional change is intended for xtensa, either. This is rather a fix for parisc because arch/parisc/Makefile defines UTS_MATCHINE depending on CONFIG_64BIT, therefore cc-cross-prefix is not working in Kconfig time.
