powerpc build attempts to cross when it's native and fails

[Robert C Jennings]

When running in the buildd I see "cross=true" and the code goes off to use qemu-powerpc-static (which isn't installed). I see "arch: powerpc rel: yakkety host_arch: ppc" so maybe you have a bad comparison/lookup as these are the same, right?

Or we can stop trying to build powerpc entirely, but thought you'd like the log if you wanted to fix it.
