When building the related C libraries you also need to specify the
--sysroot to point to the DragonFly tree, otherwise it's building the
libraries targeted at DragonFly but with Linux header files, which
clearly is *wrong*. Actually I wasn't able to cross-compile LLVM. Also
when using the --target approach, I always had to wait for hours until
it finished the Linux (host) build before it started to build the
target. I think I was just waiting too much time for compiles to finish.
If someone else figures out how to cross-compile to DragonFly with the
--target approach I am happy to know :).
