Oops.  Understandable desire, you're right of course.

It's part of GNU binutils, which I thought we required to build the
kernel anyways?

It tests based on the assumption that it's either 4K or 8K aligned.

We figured that requiring perl to build was probably a bad idea.  Not
that this whole thing isn't already a bad idea... :)

I'll make some changes to make it more friendly.
