When include/applets.h is re-generated
it generates code macros in include/applets.h e.g.
IF_XZCAT(APPLET_ODDNAME(xzcat, unxz, BB_DIR_USR_BIN, BB_SUID_DROP, xzcat))
...
IF_CHVT(APPLET_NOEXEC(chvt, chvt, BB_DIR_USR_BIN, BB_SUID_DROP, chvt))
...
sed is used to process source files like below to feed into this header
generation
sed -n 's@^//applet:@@p' "$srctree"/*/*.c "$srctree"/*/*/*.c
this means we let shell decide the order of .c files being fed into sed
tool, applets.h has code snippets thats generated out of code fragments
from these .c files and the order of the generated code depends on the
order of .c files being fed to sed and then piped to generate tool, even
though the generated code is logically same, it does result in re-odered
code in applets.h based on which shell was used during build on exact busybox
sources since sort order is different based on chosen locale and also default shell
being bash or dash
This sets the environment variable LC_ALL to the value C, which will
enforce bytewise sorting, irrespective of the shell
