is different than the "machinename" internal variable, read
machinearch's files.${machinearch} and add it to the list of files
for the machine. Also, regardless of whether or not they're different,
create a ${machinearch} sylink (or directory) pointing to the machinearch
include files (or containing them).
and files.kernel has now been completely replaced.
features supported: not nearly as broken as the stuff before
expression support for dependencies
support for 'requires'
no longer generates lots of stupid unnecessary .h files
broke lots of broken stuff, and forced fixing it.
(docs to arrive later)
added '-k' option for continue even after error
documented '-g'
