[Buildroot] [PATCH 1/6] support/scripts: add script to test a package

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

Hello,

For some reason only your cover letter had PATCHv3, not the patches
themselves. Could you check what happened?

First of all, thanks for taking over my initial crappy submission and
making it something production ready. I've applied your patch, but I
nonetheless have a few comments about it. See below.

> +    opts="$( getopt -n "${my_name}" -o "${o}" -l "${O}" -- "${@}"  )"

I continue to terribly dislike this whole concept of putting a space
after an opening parenthesis and before a closing parenthesis.

I know this is your coding style, but it is *not* the Buildroot coding
style. So I'd appreciate if the shell scripts could also comply with
the Buildroot coding style on this.

I find all these prints to be really useless, and they clutter the
output for nothing. My original script had a very lean and readable
output:

	<toolchain>:	<status>

and now it's the much more verbose (and useless):

                armv5-ctng-linux-gnueabi: download config, olddefconfig, build: OK
              armv7-ctng-linux-gnueabihf: download config, olddefconfig, build: OK

(which would get even more verbose if I had passed a -p option, since
dirclean would have been added).

I'd really prefer if we got rid of those additional prints, they are
not useful, and make the whole thing less readable.

Thanks!

Thomas
