[Click] click-mkmindriver and roofnet

[Eddie Kohler]

Hi Bob,

We finally figured out what was going on here.

A while ago the Click build process changed, making static_initialize() and 
static_cleanup() method detection more precise.  Unfortunately we forgot to 
update click-mkmindriver to generate the required annotations.  This has been 
fixed; please give it a try.  You will also need to give mkmindriver an "-E 
IPNameInfo" argument.
