only adds support for kernel-toolchain, however it is expected further changes to add kernel and userland support will be committed as they are reviewed. As our copy of binutils is too old the devel/aarch64-binutils port needs to be installed to pull in a linker. To build either TARGET needs to be set to arm64, or TARGET_ARCH set to aarch64. The latter is set so uname -p will return aarch64 as existing third party software expects this.
