I would test for CPU_TYPE instead of the target, since au1000 is not
the only one we support which is mips32r1 only. So something like:

$(ifeq $(CONFIG_CPU_TYPE),"mips32",--disable-mips32r2) would probably
work just fine. Anything that is mips32r2 sets a different CPU_TYPE,
such as 24kec+dsp, 34kc, 74k or even mips32r2.
