[Buildroot] [PATCH 3/3] armbian-firmware: fail build for missing file

[Yann E. MORIN <yann.morin.1998@free.fr>]

Ricardo, All,

I gues you wanted to Cc me on the first patch in the series, related to
linux-firmware, not armbian-firmware, right? ;-)

On 2018-01-14 21:41 -0200, Ricardo Martincoski spake thusly:
> When a file is listed to be installed but is missing from the package
> source currently the first tar command exits with error code but it is
> ignored and the build succeeds.
> This issue by itself is minor because those listed files that are
> present in the package source get installed to the target.
> But the code is currently error prone, e.g. to a typo in the file list.
> 
> Fix this by first creating a tarball in the build directory and then
> installing it, instead of using a pipe between the two tar invocations.
> Also use && between the commands, so the first command that exits with
> error code fails the build.
> Since the two tar invocations remain in use, the desired behavior
> remains the same:
>  - list of files can contain *;
>  - list of files can contain file inside path, and the path is then
>    replicated in the target;
>  - symlinks are not followed but are installed.
