Fix build for O32 systems without a TARGET_CPUTYPE defined. We must default to

Browse Source 
MIPS-III because FreeBSD relies on a number of MIPS-III features; the ABI
default would be MIPS-I which we don't intend to support.  Our old default
before I switched to using the ABI default was MIPS32.

# default ISA to be able to link against what's in /usr/lib. Terrible stuff.
