New Revision: 240967
URL: http://svn.freebsd.org/changeset/base/240967

Log:
   - Allow cross-architecture builds with 'generate-release.sh', which
     is set by specifying '-a <arch>'.  (Only supported for i386 on amd64
     and powerpc on powerpc64 currently).
   - Change how textproc/docproj is installed:
     o Attempt to install from pkg(8);
     o Fall back to pkg_add(1) if pkg(8) installation is not
       successful;
     o Fall back to installing from ports as last resort.
   - Ensure the script is run by root[1].
   - Get OSVERSION from param.h[1].
