Masahiro Yamada 77a88274dc kbuild: replace LANG=C with LC_ALL=C
LANG gives a weak default to each LC_* in case it is not explicitly
defined. 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.

To extract the kernel vmlinux, System.map, .config or initrd from the zImage binary:

objcopy -j .kernel:vmlinux -O binary zImage vmlinux.gz
objcopy -j .kernel:System.map -O binary zImage System.map.gz
objcopy -j .kernel:.config -O binary zImage config.gz
objcopy -j .kernel:initrd -O binary zImage.initrd initrd.gz
