# The aarch64 wheels are being crosscompiled to allow running the build
# on x64 machine. The dockcross/manylinux2014-aarch64 image is a x86_64
# image with crosscompilation toolchain installed.
# Use an older version of dockcross image that has gcc4.9.4 because it was built
# before https://github.com/dockcross/dockcross/pull/449
