# 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 v7h
#  - patch to fix webrtc code for non-android ARM
#  - patch (hack) to fix skia
#  - makeflags to -j3, seems to barf higher
#
#        moonman <moonman [dot] ca [at] gmail [dot] com>
#  -added armv6 support
