commit: https://git.buildroot.net/buildroot/commit/?id=434967638490a2c06c99723a39d82826bdb67c35 branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master This patch adds support for the powerpc arch to conditionally check if an arch provies altivec accelerator support, similar to other SIMD on ARM/x86. Upstream issue: aircrack-ng/aircrack-ng#1941 Fixes http://autobuild.buildroot.net/results/87e82a5e8d0b1c1ff10ec3e59d25bcd56b329075 Tested against both a e6500 with Altivec and a e500 target.
