Port Sage to SUSE Linux Power 7 (ppc64).

[williamstein]

Port Sage so that it builds and passes its full test suite on the new IBM Power 7 architecture running SUSE Linux.

This is the only test failure with sage-5.12.beta1:

I am actually in the process of commissioning such hardware and suse will be on some nodes (Aix 6.1 on the other nodes).

fbissey -- do you want an account on skynet, so you can help us with porting to SUSE on a nice new "IBM Power 750 Express server" that we have?

This is the computer we have access to: http://www-03.ibm.com/systems/power/hardware/750/index.html

We are getting 13 power755 locally but they'll go live at the end of September - I am currently installing a power720 that is meant to be a deployment server. Got a BlueGene/L and BlueGene/P as well but that would be another exercise :)

The big pity as far as I am concerned is that there is no Gentoo-prefix for linux-ppc otherwise I could have been up and running faster.

We currently have some power5 575 some of which are running suse 9 and that's awful, the latest gcc I have been able to compile is 4.2.4.

I notice in the build logs that you have gcc-4.6.1 on that box. Is it a manual install of gcc?

Replying to @kiwifb:

Yes. Here is some info about the machine. If you want an account on it, send me an email and I can arrange it.
