Hi,

Per bug #673116 [1], I'd like to RFC adding a new global flag:

 7z - Enable support for 7-Zip (.7z) archives

The consumers are currently split between using '7z', '7za' and '7zip'
flags:

dev-games/physfs/metadata.xml:<flag name="7zip">Enable 7zip/lzma archive support</flag>
dev-libs/poco/metadata.xml:             <flag name="7z">Add Support for the 7z archive format</flag>
games-emulation/m64py/metadata.xml:             <flag name='7z'>Ensure support for .7z archives.</flag>
kde-apps/kdeutils-meta/metadata.xml:            <flag name="7zip">Install <pkg>app-arch/p7zip</pkg> for 7zip archive support in <pkg>kde-apps/ark</pkg></flag>
media-gfx/apngasm/metadata.xml:         <flag name="7z">Enable support for 7zip compression</flag>
net-nntp/sabnzbd/metadata.xml:          <flag name="7za">Add support for extracting 7za files</flag>
