gst-libav1: explicitly specify the cpu
In the non-cross case, libav does basically the same, but with
-march=native / -mcpu=native.
Without this and gcc 7.x, the CPU for PPC is not detected correctly and
building fails with:
./libavutil/ppc/util_altivec.h:134:63: internal compiler error: Segmentation fault
