emulator-arm64: ARM64 wrapper for QEMU executable.
This patch adds two new binaries (emulator-arm64 and emulator64-arm64)
which act as a wrapper for QEMU-based emulation engines for ARM64
emulation (and ARM64 _only_).
The (prebuilt) qemu binary must be located under:
$PROGRAM_DIR/qemu/$SYSTEM/qemu-system-aarch64$EXE
Where:
$PROGRAM_DIR is the location of the 'emulator-arm64' binary.
$SYSTEM is a host system tag (e.g. linux-x86 or linux-x86_64)
$EXE is the host executable extension.
The program is in charge of parsing command-line arguments,
computing AVD configuration, then calling the QEMU program
with a (very long) list of configuration arguments.
See https://qemu-android.googlesource.com/qemu-ranchu/ for
scripts used to rebuild the QEMU prebuilt binary from
sources.
