TARGET_CPU would be a misleading name. TARGET_ARCH2 means that it's a
kind of subarchitecture. TARGET_SUBARCH or TARGET_ABI32_NAME should be
OK too.

For example, there is no CPU type (or even class of CPUs) called
sparc32plus. There is Sparc (a.k.a. Sparc32, V8) and Sparc64 (a.k.a.
Ultrasparc, V9, V9plusa etc.). Sparc32plus is a userland mode for
Sparc64 CPUs where the address space is limited to 32 bits. The same
probably applies to other 32 bit subarchitectures.
