Since we introduced the support for building Busybox as individual
binaries, Busybox started failing to build on SPARC/SPARC64 with this
feature enabled:
appletlib.c:(.text.find_applet_by_name+0x14): relocation truncated to fit: R_SPARC_GOT13 against symbol `applet_nameofs' defined in .rodata.applet_nameofs section in libbb/lib.a(appletlib.o)
appletlib.c:(.text.find_applet_by_name+0x18): relocation truncated to fit: R_SPARC_GOT13 against symbol `applet_names' defined in .rodata.applet_names section in libbb/lib.a(appletlib.o)
[...]
This commit adds two patches to Busybox to fix this issue, by adding
-fPIC to CFLAGS when building on SPARC/SPARC64. The patches have been
submitted upstream.

Currently, remounting / read-write (or not) is done by the skeleton
package when the init system is either busybox or sysvinit, by
registering a target-finalize hook; it is not done at all for systemd.
Move registering this target-finalize hook to both of busybox and
sysvinit. Leave systemd alone, we'll take care of it later.
Rename the macro to a more meaningful name, and move it to system.mk
with the other such macros.
Yet a little bit less init-system knowledge in the skeleton.

Currently, setting the getty is done:
- by the skeleton package when the init system is either busybox or
sysvinit;
- by the systemd package when the init system is systemd;
both by registering a target-finalize hook.
This is not very consistent.
Move setting the getty out of the skeleton and into the package that
provides the init system, by registering a per-package target-fialize
hook.
This offloads yet a bit more out of the skeleton, so that it is easier
to properly separate the skeletons for the various init systems.

FEATURE_CLEAN_UP is a configuration feature to get busybox to explicitly
call free() on dynamic allocated memory just before exiting so memory leak
detectors like valgrind don't get confused. Upstream explicitly recommends
to NOT enable this option:
config FEATURE_CLEAN_UP
bool "Clean up all memory before exiting (usually not needed)"
default n
help
As a size optimization, busybox normally exits without explicitly
freeing dynamically allocated memory or closing files. This saves
space since the OS will clean up for us, but it can confuse debuggers
like valgrind, which report tons of memory and resource leaks.
Don't enable this unless you have a really good reason to clean
things up manually.
Having this option enabled adds a bit of bloat, but more significantly these
cleanup code paths don't get tested very often so some times get out of sync
with the allocation code which can lead to crashes (or security issues from
double frees), so it is safer to disable the option.
For people wanting to debug memory leak issues with busybox, the option can
still be enabled with a configuration fragment (or a custom config).
The size difference isn't huge (br-arm-full-static):

that link against a shared library.

Removing clear and reset from the busybox config when the ncurses tools
are enabled is not really needed.
Since commit 802bff9c42, the busybox install will not overwrite
existing programs. Therefore, the tools will be installed correctly
regardless of the order of the build:
- if busybox is built first, the clear and reset apps are installed,
but they will be overwritten by ncurses;
- if ncurses is built first, it will install the clear and reset apps,
and busybox will no longer install them.
We prefer not to modify the busybox configuration when not strictly
necessary, because it is surprising for the user that his configuration
is not applied. Clearly, it's not ideal that busybox is configured with
redundant apps, but if the user wants to shrink it, it's possible to
provide a custom config.
This partially reverts commit 33c72344a8.

BR2_PACKAGE_BUSYBOX_SHOW_OTHERS is a bit special. When Busybox is
enabled, it is a Busybox option. When Busybox is not enabled, it is a
stand-alone option, forcibly enabled.
So we can safely 'select' it without ensuring (via a 'depends on' or
another 'select') that Busybox is enabled.
However, the name of this option does not express the fact that it is
safe to select it without checking Busybox, which can lead to a bit of
time-consuming head-scratching.
To avoid future puzzlement from an unsuspecting observer, add a a big
fat comment that this option can be selected without any dependency on
Busybox.
