DJ, I don't have intimate knowledge of these bits, but I don't see how
GCC's knowledge of FPU is, or should be, EABI-specific.  I think you
should start by looking at the EABI behavior, and seeing if you think
it's problematic.  If it isn't, then you can either punt on arm-elf, or
enable some EABI functionality there.  If, on the other hand, you think
there's a problem when using the EABI, then we should talk about how to
solve it.
