The change in bootstrap have serious impact in bulk build.
System with 
 need_awk=yes
in boostrap can't make a bulk build.

when building lang/nawk the awk build is NOT PRESERVE and is deleted after 
'bmake package'.

impacted system are:


HP-UX
IRIX*
SunOS
AIX
Interix
UnixWare
OSF1
   and the --full option of boostrap
   
Suggest is to create a pkgtools/nawk like pkgtools/pax and call it in bootstrap.
look also at pre-build and make this package broken (like pax)
roughtly look at pax and do same thing for nawk.

My wish is to make a bulk build before my holidays ;)
