release(8) environmental variables

[Brian A. Seklecki]

As far as building goes, the variables in play are:

   DESTDIR, MAKEOBJDIRPREFIX, RELEASEDIR, CHROOTDIR, CVSROOT,
   EXTSRCDIR, EXTDOCDIR, BUIILDNAME, RELEASETAG, NODOC, NOPORTS,
   WORLD_FLAGS, LOCAL_SCRIPT

For stage one of the release process, the following seem relevant:

   DESTDIR, MAKEOBJDIRPREFIX, RELEASEDIR

For stage two:

   CHROOTDIR, CVSROOT, EXTSRCDIR, EXTDOCDIR, BUIILDNAME, RELEASETAG, NODOC,
   NOPORTS, WORLD_FLAGS, LOCAL_SCRIPT


Do you guys prefer to set these in make.conf(5) or as exported 
environmental variables in the shell that spawn's make(1) ?
