    i386: Fix build (of 'genassym.o')
    
    i386's genassym.c needs to define some assembly symbols holding the size
    of NFS structures to support NFS_ROOT while booting with a nfs_diskless
    structure.  For this, it needs to include a few NFS headers, which
    require definitions from <sys/mount.h> (fhandle_t, vfs_init_t), which
    was removed by commit 72ab129799a2 ("x86: remove sys/mount.h from
    genassym.c").
    
    Since recently, <sys/mount.h> has been including <sys/vnode.h>, so needs
    "vnode_if.h" to have been generated for the compilation of 'genassym.o'
    not to fail.  Make sure this is the case (for all architectures for
    simplicity) by tweaking the rule for 'genassym.o' in
    'sys/conf/kern.post.mk', leaving a comment there so that it can be
    removed when i386 is dropped (or if the above-mentioned dependency is
    broken).
