libopenssl needs atomic or the build will fail (e.g. on sparcv8 without
libatomic):

It should be noted that openssl3 has added OPENSSL_DEV_NO_ATOMICS but
"this is intended for internal development only, to check the
refcounting is properly coded. It should never become a configuration
option, hence the name of the macro.":

Atomics are not available in Buildroot if:
- architecture is 32 bit and something other than ARM or xtensa, and
- GCC < 4.8 or no threads or FLAT.
The nothreads case can theoretically happen in many different
situations, but in practice nobody disables threads. So the only
interesting case is the FLAT case. Since ARM and RISC-V 64 both have
atomics intrinsics, that leaves just m68k NOMMU as FLAT. So this is
truly a corner case.
The proper solution would be to patch GCC to also provide libatomic in
those cases.
- For nothreads, atomics are in fact not needed, so libatomic can simply
be implemented as stubs.
- For FLAT, it's probably just a matter of having a match to uclinux in
libatomic/configure.tgt.
Again, though, this happens only in such niche cases that it's not worth
working on it.

This directory contains various useful scripts and tools for working
with Buildroot. You need not add this directory in your PATH to use
any of those tools, but you may do so if you want.
brmake
a script that can be run instead of make, that prepends the date in
front of each line, redirects all of the build output to a file
("'br.log' in the current directory), and just outputs the Buildroot
messages (those lines starting with >>>) on stdout.
Do not run this script for interactive configuration (e.g. menuconfig)
or on an unconfigured directory. The output is redirected so you will see
nothing.
check-package
a script that checks the coding style of a package's Config.in and
.mk files, and also tests them for various types of typoes.
genrandconfig
a script that generates a random configuration, used by the autobuilders
(http://autobuild.buildroot.org). It selects a random toolchain from
support/config-fragments/autobuild and randomly selects packages to build.
get-developers
a script to return the list of people interested in a specific part
of Buildroot, so they can be Cc:ed on a mail. Accepts a patch as
input, a package name or and architecture name.
scancpan
a script to create a Buildroot package by scanning a CPAN module
description.
scanpypi
a script to create a Buildroot package by scanning a PyPI package
description.
size-stats-compare
a script to compare the rootfs size between two different Buildroot
configurations. This can be used to identify the size impact of
a specific option, of a set of specific options, or of an update
to a newer Buildroot version...
test-pkg
a script that tests a specific package against a set of various
toolchains, with the goal to detect toolchain-related dependencies
(wchar, threads...)
