freebsd-nq/sys/conf/Makefile.i386
Peter Wemm d061973c76 Create a special option file "opt_global.h" which is included by all
source files via a 'cc -include opt_global.h ...' type arrangement.
This means we can untangle certain header files.

options.i386 has a placeholder until it has a real member so we can avoid
having to teach config about it just yet.

# Generic makefile changes should be made in
# /sys/i386/conf/Makefile.i386
