The powerpc support in this package requires an arch with altivec
accelerator support. The package is currently just building powerpc
assuming a Power8\Altivec.

This looks like the wrong fix. The Altivec code in Aircrack-ng is not
mandatory, just like the ARM NEON code is not mandatory. There is some
other issue that causes the build failure.
