undocumented HISTORICAL_MAKE_WORLD variable and set it. Note it
here so the blow up will not really be a surprise to people who
read.
Link the buildingworld chapter of our handbook in the README
while I'm here.
`buildworld' is no longer a strict prerequisite for `buildkernel'
as of Makefile.inc1,v 1.184.
Fix kernel configuration files path to look MI.
Mention src/kerberos5.
- Make world doesn't build the modules any more.
- Mention the buildkernel/installkernel targets as common used targets.
- LINT has gone, NOTES is new but cannot be built. It is a pure reference
file. However, I still mentioned LINT but pointed out the difference
between the ancient LINT and the new NOTES. This should avoid confusion.
- crypto/ subdir isn't export controlled any more.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
