And _this_ line is still MACHINE_ARCH here, which is wrong. This should use
MACHINE_CPUARCH. That is the only line I have been talking about the entire
time.

Note here how in the Warner's diff, he replaced one use of MACHINE_ARCH (the
amd64 and i386 comparisons) and one use of MACHINE_CPUARCH (the other cases)
with always using MACHINE_CPUARCH.

svn did the right thing. The code was broken before Warner's fix. To be
clear, this is all I think needs to change:
