Yea, we got nothing that’s for that use case. toolchain is for the weird world that we build /usr/src in. xdev is for building mips on x86 when the rest of the tree is x86. You’re wanting native binaries when the rest of the world is mips but that behave like the world is mips so that when invoked in the typical ports way, it just works. I don’t think xdev will do that because the paths are messed up and you’ll need two copies of libraries, includes, etc. It expects to be installed in /usr/$ARCH-freebsd/<mumble> and if it isn’t, it gets cranky.

Having said that, it sounds like a third way to build these may be needed. One that expects to be installed in /usr/bin, is amd64 executable, but produces mips binaries from /usr/lib, /lib, etc.
