Right now I'm using two Raspberry Pi's (2 and 3) to test CloudABI support for armv6, armv7 and aarch64. It would be nice if I could restrict this to just a single instance when testing smaller changes. This is why I'd like to get COMPAT_CLOUDABI32 to work on arm64. As COMPAT_CLOUDABI32 depends on COMPAT_FREEBSD32, at least for the ELF loading, this change adds all of the bits necessary to at least build a kernel with COMPAT_FREEBSD32. All of the machine dependent system calls are still stubbed out, for the reason that implementations for these are only useful if actual support for running FreeBSD binaries is added. This is outside the scope of this work. Reviewed by: andrew Differential Revision: https://reviews.freebsd.org/D13144
