[RFC] poky.conf: Drop CentOS 7 from supported distributions

[RFC] poky.conf: Drop CentOS 7 from supported distributions

[Krzysztof Kozlowski]

Since Yocto v3.0, the extensible SDK cannot be built on CentOS 7 because
of old tar:

    $ bitbake xxx-image -c populate_sdk_ext
    Your version of tar is older than 1.28 and does not have the support
    needed to enable reproducible builds. Please install a newer version of
    tar (you could use the projects buildtools-tarball from our last
    release).

Drop it then from officially supported distributions.

The plan is to suggest people use buildtools-tarball on such systems
and there are open bugs for this.

Cheers,

Yes, I understand the suggestion but the message is hidden behind
big-red-error with last lines:
    Exception: FileNotFoundError: [Errno 2] No such file or directory: 'build/tmp/work/col_vf50_proceq-poky-linux-gnueabi/console-proceq-image/1.0-r0/sdk-ext/image//opt
    /eagle/3.0.2/conf/local.conf.bak' ->
'build/tmp/work/col_vf50_proceq-poky-linux-gnueabi/console-proceq-image/1.0-r0/sdk-ext/image//opt/eagle/3.0.2/conf/local.conf'

So the user might not even spot the suggestion.  The second point is
that if by default distribution cannot compile one of basic features of
Yocto, then I doubt that it has the same level of support as others.

Best regards,
Krzysztof
