bash has a concept of "loadables", which are "plugins" that can be
loaded at runtime by bash to add new builtin. For example:
# type whoami
whoami is hashed (/usr/bin/whoami)
# whoami
root
# enable -f /usr/lib/bash/whoami whoami
# type whoami
whoami is a shell builtin
# whoami
root
# enable -d whoami
# type whoami
whoami is hashed (/usr/bin/whoami)
# whoami
root
bash comes with a set of example loadables, installed in
/usr/lib/bash/. They take 312 KB on ARM32, and are by default not
used, and provide builtins that are for the most part already
available as external commands in Busybox/coreutils:
Makefile.inc finfo mkfifo realpath sync
accept head mktemp rm tee
basename id mypid rmdir truefalse
csv ln pathchk seq tty
cut loadables.h print setpgid uname
dirname logname printenv sleep unlink
fdflags mkdir push strftime whoami
So instead of having them unconditionally installed, add an option to
enable/disable their installation (their build apparently cannot be
disabled via a configure option).
Normally, we try to keep backward compatibility by preserving the
existing behavior. In this case, this would have meant making this
option "default y". But this also breaks our principle of "being
minimal by default", and in this case, it feels preferable to be
"minimal by default" than preserving existing behavior.

The check-package script when ran gives warnings on ordering issues
on all of these Config files. This patch cleans up all warnings
related to the ordering in the Config files for packages starting with
the letter b in the package directory.
The appropriate ordering is: type, default, depends on, select, help
See http://nightly.buildroot.org/#_config_files for more information.

Having the BR2_PACKAGE_BUSYBOX_SHOW_OTHERS dependencies in
package/Config.in is not very practical: it makes this file not very
readable, and puts the dependency away from the package itself, which
can sometimes be confusing. Therefore, this commit moves the dependency
in each package Config.in file.
