Not a problem. We could do the same thing as we've done for
DEFAULT_ABI. Declare rs6000_fprs to be an enum. #define TARGET_FPRS
to a known value in the individual system .h files. And define
TARGET_FPRS to rs6000_fprs if the macro is not defined.
I can do this if you want.

Nope. Absolutely not. Only eabi + spe abi extensions.
