Vincent Stehlé c9dca7f4c3 utils/brmake: filter output for parallel build
When building in parallel with per-package directories
(BR2_PER_PACKAGE_DIRECTORIES=y), brmake output is often garbled:

  2025-10-08T18:39:10 >>> host-dtc 1.7.2 Building
  2025-10-08T18:39:11 checking for stdint.h... >>> host-dtc 1.7.2 Installing to host directory
  2025-10-08T18:39:12 checking for limits.h... >>> host-gmp 6.3.0 Installing to host directory

Remove the spurious string between the timestamp and the ">>>" marker to
fix this.
We need some extra care to preserve the preceding "term bold" special
characters sequence.

We also prevent grep and sed to buffer their output too much. This leads to
more frequent output even when we might not be connected to a terminal; for
example: when brmake's output is piped to another program or when running
in CI.

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 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...)
