Support for Linux/OSX ARM64

[martin-g]

Hello,

I'd like to request for support for ARM64 CPU architecture.
There are several binaries in the bin/ folder which are pre-built for x86_64.

bin/GapCloser:               ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.9, not stripped
bin/k8-Linux:                ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.18, BuildID[sha1]=06cc284c2e91a5efb66827316bea05be2daffea1, stripped
bin/platanus:                ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.18, BuildID[sha1]=6d3322dd6167b67e95b90e65fb881c2cc18dc616, not stripped

Would it be possible to either provide pre-built binaries for arm64/aarch64 or make so that they are part of the build process ?
Or document that those are third-party requirements which should be provided by other means,

Thank you!
