Yann E. MORIN 3aacb38098 utils/brmake: drop use of unbuffer
When it was introduced in afdb545b28 (tools: new tool to filter the
output of make), brmake made use of unbuffer, so as to try and ensure
that no output would get lost between make printing it, and the logger
loop time-stamping it and storing it in the logfile, in case the user
would interrup the build (SIGINT, ^C)

However, unbuffer is missing in our reference build image (we could have
added it, but we missed the occasion to do so every time we updated the
reference build image).

Furthermore, the rationale for using unbuffer, although reasonable, is
not so practical: indeed, when the user hits Crtl-C, this is inherently
asynchronous, and they can't expect everything to be entirely cleanly
terminated, especially buffering. Using unbuffer is thus slightly
superfluous.

The timestamps will be slightly off because of buffering, but a build
generates so much output that this won't be a problem in practice.

Drop use of unbuffer.

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.
    To run this within a container using docker-run (see below), set
    BR2_DOCKER=y in the environment, i.e. call it as
    `BR2_DOCKER=y utils/brmake`.
    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 across the buildroot tree. It
    checks package's Config.in and .mk files, runs shellcheck for all shell
    scripts, flake8 for python files, checks for typos, etc.
    It checks the .checkpackageignore file if errors should be ignored and
    errors if there's a file listed that doesn't produce an error.

docker-run
    a script that runs a command (like make check-package) inside the
    buildroot CI docker container; pass no command to get an interactive
    shell.

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...)
