The LINT file moved from a static file to a dynamically-generated file a 
while ago since not all options are applicable for all platforms.

A generic NOTES file (in /usr/src/sys/conf) is combined with a 
platform-specific NOTES file (in /usr/src/sys/<platform>/conf, where 
<platform> is i386, amd64, pc98, etc) to create the LINT file.

$ cd /usr/src/sys/i386/conf
$ make LINT
cat ../../conf/NOTES NOTES | sed -E -n -f ../../conf/makeLINT.sed > LINT
