I disagree.  For example, the unmodified crc32.c in libkern does byte
order checking at runtime, which is just pointless in the kernel.  The
libz source is so dirty, if we have to clean it up at all for in-kernel
use, better, I think, to just extract the useful part of that file and
maintain it ourselves.

It is my intent to add a _much_ smaller crc32 function for use by
STANDALONE so that even libz built into the bootblocks doesn't use the
code from common/dist/libz.
