kldxref: file isn't dynamically-linked - technical reason for this error message?

[Garrett Cooper]

	I'm doing a clean install of 7-CURRENT from 6.2-RELEASE and I see the 
following message at the end of make installkernel:

kldxref: file isn't dynamically-linked

	All I've seen on the lists I've found via Google is a lot of "don't 
worry about the message -- it's not important" replies, but I've never 
seen this before, and I was wondering what the technical reason was 
behind the message.

Thanks,
-Garrett
