tools: new tool to filter the output of make



Add brmake, a small script that redirects the build output log to a
file, keeping just Buildroot's own messages, with the date+time added
at the start of the line.

We need to unbuffer the output of make so that, when the script is
interrupted (SIGINT, ^C), there is no lingering output not yet digested
by the logger loop.

......@@ -2,6 +2,15 @@ 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.
