Add PowerPC support about hwinfo

[lfreist]

Hi,
hwinfo should work architecture independent on Linux, Windows and Mac (development for MacOS is not very far...).

The supported (and yet unsupported) features for each platform stated here should work on any architecture.

Have you already tried building and running hwinfo on a PowerPC?

If so, it would be nice, if you can provide further information on whats unexpected/not working.

I apologize, this went forgotten. I will do this today.

Thank you! It's a pure failure from my side. Didn't have a non x86 Mac for testing thins peace of code... However, I found the bug and will fix it later.

@lfreist I will try and update you.

@lfreist Build fails here for me:

Types of PPC cpus can be found in /usr/include/mach/machine.h.
This is how it can be determined: https://www.eidos.ic.i.u-tokyo.ac.jp/~tau/lecture/parallel_distributed/2016/examples/09mm/OpenBLAS/cpuid_power.c

@lfreist Great, thank you!

[lfreist]

commit ba3ba8b should fix the stated issue. Since I cannot test for non x86 MacOS, I cannot assure that there are no other issues... Would be grateful, if you can provide further information after testing the new commit!

@lfreist Thank you. There is this error then:

Destroot does not work too, but that is trivial to fix on our end.
