68k cross-development on FreeBSD (or any other unixlike platform) is pretty straightforward. Crosstool-NG trivialises generating the toolchain, and the current state of 68k support in the FSF tools is quite good. LLVM is getting there, but I feel like the backend needs more work.
Unless the NuttX cross-compilation tooling has changed drastically, I wouldn't expect you'll need to do anything substantially different from any other GCC-based target. Thinking a bit more about the issue I got stuck on, I suspect it may have been related to not having a standardised way to generate a deferred interrupt akin to PendSV. I was doing a lot of ARMv7M work at the time, and I was probably trying to exploit the otherwise fairly similar nature of the two architectures.
