This is the same difference as between sparc and sparc64/sparcv9: while
all recent SPARC CPUs are capable of executing 64-bit insns, there's
both a 32-bit ABI (sparc) and a 64-bit one (sparcv9/sparc64).
On MIPS (at least IRIX and obviously Linux/MIPS as well), you have two
32-bit ABIs (O32 and N32) and one 64-bit one (N64), on other systems
there's also O64.
It again comes down to what GOARCH is supposed to mean: an ABI, or what
else?
