[Powertop] Gentoo: v2.6.1 breaks packaging traditions

Hey gang,

In hacking together a package (ebuild) for Gentoo, two issues
complicated what should otherwise have been a trivial update.

1) There are two release tarballs for the version. The first of these
was pointed to by default when I made my initial pass-- assumption was
that the "powertop-2.6.1.tar.gz" would be hosted on the server. I was
right. However, that tarball resulted in a broken build.

https://01.org/sites/default/files/downloads/powertop/powertop-2.6.1.tar.gz

https://01.org/sites/default/files/downloads/powertop/powertop-2.6.1.tar_0.gz

2) Further, the second tarball URL (found on 01.org mousing over links)
ends in "tar_0.gz", which breaks with filename convention and also
breaks Gentoo's out-of-the-box 'unpack' packaging function.

Are there any plans to remedy this?

Cheers and thanks
