Yes, but presumably you could make those pseudo-ops ARM-specific, rather
than EABI specific?

It's pretty dead. Richard Earnshaw recently suggested deprecating
arm-elf in GCC 4.6. I think that's reasonable; most of the major
operating systems (not just GNU/Linux, but embedded operating systems
too) have switched to the EABI, not just for compatibility with one
another, but because it's technically superior.
