GOARCH=amd64 ./build.sh

syso/goboringcrypto_linux_arm64.syso is built with:

	GOARCH=arm64 ./build.sh

Both run on an x86 Debian Linux system using Docker.
For the arm64 build to run on an x86 system, you need

	apt-get install qemu-user-static qemu-binfmt-support

to allow the x86 kernel to run arm64 binaries via QEMU.

To run the standard library tests, enable Cgo and use an appropriate
C compiler from the Android NDK. For example,

	CGO_ENABLED=1 \
	GOOS=android \
	GOARCH=arm64 \
	CC_FOR_TARGET=$NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android21-clang \
	./all.bash

To run tests on the Android device, add the bin directory to PATH so the

# This uses the latest available iOS SDK, which is recommended.
# To select a specific SDK, run 'xcodebuild -showsdks'
# to see the available SDKs and replace iphoneos with one of them.
