[Rpm-maint] RFC: yum+rpm ppc64p7 patches

[Phil Knirsch]

Hi folks.

Here the promised patches to add support for adding a power7 optimized 
arch to ppc64 for rpm and yum.

It's pretty similar to the ARM neon support code from dgilmore, only 
that i needed to add the detection properly in rpm as well.

I've tested them to some degree with a local repository containing 
packages build with --target ppc64p7 and then installing, removing and 
updating the respective package. Selection worked as expected, preferred 
ppc64p7 obviously on a Power7 box.

The detection code is a bit rough, both in yum and rpm, but i didn't 
want to manually parse the C struct from /proc/self/auxv.

Let me know what you think of them. The toolchain guys i spoke with at 
least were already pretty curious about it as they'd like to use it at 
some point as well.

I'm on PTO next week, so no rush :)

Thanks & regards, Phil
