Yeah, a couple of minor fixes there that I forgot to mention in the log.

Thanks for that review -- m68k assembly isn't my strongest language. The
kludge to return pointers in both d1 and a1 was a bit ugly, but seemed
like a much more robust plan than attempting to use different registers
depending on the target ABI...

The real check for these fixes was to run a fairly comprehensive C
library test suite (part of picolibc) and just iterate until I stopped
getting failures. Those tests have found so many corner cases in both
the C library, FPU emulation and compilers ...
