Original issue's description:
> Flip Linux x64, linux_chromium_archive_rel_ng bots to GN
>
> This patch adds MB support for the new 'linux_chromium_archive_rel_ng'
> bot and flips it and the 'Linux x64' waterfall bot to GN.
>
> This bot should replace the 'linux_chromium_clobber_rel_ng' bot ASAP
> since that bot is doing a GYP build of 'chromium_builder_tests',
> which isn't that interesting, and the supposed builder that that bot
> is mirroring, 'Linux Builder (clobber)' on the chromium.fyi waterfall,
> doesn't actually exist.
