Add reach-over include files to read i386/foo.h. In time, the pc98
specific code will migrate to these files to augment or replace the
version in i386/include and/or i386/linux. This should, in the
fullness of time, allow many of the #ifdef PC98 in the tree.

# These files are in the public domain because there is insufficient
