[LV] The kernel build process & tools any changes .

 	I stand corrected my i386 linux-tree does have a link such as :

  root at filesrv1:~ # dir /usr/src/linux-2.6.18.3/include/
total 184
  4 drwxrwxrwx   41 root root  4096 2006-11-18 22:58 ./
  4 drwxrwxrwx   20 root root  4096 2007-01-05 20:01 ../
  4 -rw-rw-rw-    1 root root   161 2006-11-18 19:28 Kbuild
  4 drwxrwxrwx    3 root root  4096 2006-11-18 19:28 acpi/
  0 lrwxrwxrwx    1 root root     8 2006-11-18 22:58 asm -> asm-i386/

 	This brings up the lack of a mutex.[ch] and that for some reason we 
don't create the above link into our 'include/vax-asm' ,  which s/b auto-magic 
as far as we are concerned .  But undoubtedly soem place else needs patching .
