Christ.

I grepped for this, and couldn't find any use of that memblock_free
function in the tools directory, so I ignored it.

It seems like the code in lib/bootconfig.c is compiled both into the
kernel and into that tool. This is a nightmare. We've explicitly tried
to avoid this for the tooling headers exactly because of issues like
this.
