# Building for x86_64 requires lib32-glibc & lib32-zlib from [multilib]. These
# libraries are linked from the NaCl toolchain, and are only needed during
# build time.

# ALARM: Kevin Mihelich <kevin@archlinuxarm.org>
#  - removed NaCl, not for ARM
#  - adjusted gyp flags for v7/aarch64
#  - makeflags to -j4 on v7, RAM constraints
#  - Gentoo patch to remove lingering built-in ffmpeg code
#  - upstream patches to fix AArch64
