MFH r257801:
  - Update release noted to DocBook 5.0 so that they work with the new tree
MFC r257658:

For C++ programs, don't emit any explicit dependency to libstdc++.a or
libc++.a during the early build stages (bootstrap-tools, build-tools,
cross-tools), since it is not possible to know in advance which C++
library is available on the host system.

Instead, just use the bootstrap compiler's built-in default.  This
should eventually make it possible to build stable/9 on head, or on
stable/10, which ship without libstdc++ by default.
Update comments in release/Makefile.inc.docports to reflect the
cvs->svn conversion over a year ago.

This is a direct commit to stable/9, as this file does not exist
in higher branches.

Remove evaluation of OSVERSION < 500000.
I hope to never have to build a release from a stable/5 machine.

While here, remove hard-coded lang/perl5.10, which is better
evaluated during compile-time (especially since lang/perl5.10 does
not exist in the ports/ tree).

This is a direct commit to stable/9, as this file does not exist in
higher branches.

Regenerate MINIMALDOCPORTS after the doc/ toolchain update to
docbook 5.0.

This is a direct commit to stable/9, as this file does not exist
in higher branches.

(Although, I do not think that this variable is actually used
now, since we check out the full doc/ tree from svn.)

MFC r257641:
 When building the textproc/docproj port, the ports-mgmt/pkg port
 needs /var/run/ld-elf*.so.hints, which is not automatically created.

 Fix reldoc build by running the ldconfig(8) startup script in the
 chroot directory before starting the port build phase.
