# To run NaCl on CrOS ARM64, we use a nacl_helper binary which gets built for
# ARM32. is_minimal_toolchain indicates that we are currently building this.
# This is required because the Chrome OS build makes only a minimal set of ARM32
# libraries available inside an ARM64 build, which means we need to limit the
# (indirect) dependencies of nacl_helper.
# Note that this is different from is_nacl in that we are not actually using a
# nacl toolchain to compile nacl_helper.
# See https://crbug.com/1339021 for more details.
