ppc: force target cpu
With gcc-5.2 default target is power7.
- For 32-bit PPC builds set the target cpu to 604 in order to support PReP as
well as Macs in the future.
- For 64-bit PPC builds set the target cpu to 970 as used in 64-bit Macs but
disable altivec.
Based on an original patch by Laurent Vivier <laurent at vivier.eu>.
