I have a work-in-progress branch on GitHub < https://github.com/arichardson/freebsd/tree/crossbuild-aug2018>; (warning: I rebase this branch whenever I commit one of my changes) but I haven't written up anything about the current state. I have a few pending patches on phabricator and some committed changes but the rest of the changes still needs some clean-up before it can be submitted. Most of the changes are just allowing to build one of the bootstrap tools on non-FreeBSD but there are also two bigger changes (D16815 and D14316) to provide the basic cross-OS building infrastructure. It currently works fine for me on MacOS and Linux when compiling with the CHERI fork of llvm/clang/lld (<https://github.com/CTSRD-CHERI/clang>) but in order to compile with upstream clang you will have to delete the builtin std* headers from the clang install since they are incompatible with the FreeBSD stddef.h/stdio.h/etc. headers. If you want to try it out you should to use the script tools/build/make.py instead of make and if you're lucky `make.py buildworld` might succeed. I've tested building for mips64 and amd64 but other architectures might also be fine.
