#   ARM64 (aka ARMv8) <- only supported on linux and darwin builds (go1.6)
#   ARMv7
#   ARMv6
#   ARMv5
#
# Some words of caution from the master:
#
#   @dfc: you'll have to use gomobile to build for darwin/arm64 [and others]
#   @dfc: that target expects that you're bulding for a mobile phone
#   @dfc: iphone 5 and below, ARMv7, iphone 3 and below ARMv6, iphone 5s and above arm64
