I'm not familar with eabi, I've not heard of it with reference to MIPS.
I'd have to ask my more learned colleagues :)
o64 is not supported on Linux, and not going to be AFAIK, but bare-iron
it would be as gcc can generate the code.
Once you have a supported ISA/ABI you can choose your endian with impunity.
