Update to 5.2.4 from Bernd Ernesti.

* Changes from 5.2.3

   1) New printers supported in this release:

      Canon PIXMA iX4000
      Canon SELPHY CP-520
      EPSON Stylus Photo R2880
      EPSON Stylus DX4000

   2) Printing to the Epson PM-D600 has been corrected.

   3) Printing using the manual sheet guide on the Epson Stylus Photo
      R2400 has been corrected.

   4) Printing to the EPSON Artisan 700 and 800 and Stylus Photo
      P/TX700 and 800 series printers has been corrected.  Among other
      issues, it should now be possible to print reliably using the
      photo tray.

   5) The names of the following Epson printers have been corrected:

      EPSON Stylus Photo PX700W
      EPSON Stylus Photo TX700W
      EPSON Stylus Photo PX800FW
      EPSON Stylus Photo TX800FW

   6) The names of various Ricoh and Ricoh-based printers have been
      corrected to match Ricoh's model names and the OpenPrinting
      database.

   7) The EPSON inkjet utility, escputil, now correctly prints the
      color name for low ink warnings.

   8) Printing resolution names have been fixed in non-English locales
      in CUPS PPD files.

   9) A Russian translation has been added.  The Danish and Italian
      translations have been updated.

   10) Support has been added for L-size paper with tear-off borders.

   11) The ordering of inks in quadtone ink sets on Epson printers has
      been corrected.  In addition, support has been added for MIS
      quadtone and 6 tone inks.

   12) It is now possible to adjust the ink parameters for quadtone
      inks in CUPS.  Previously, these parameters could only be
      adjusted in the enhanced Print plugin for GIMP and other native
      Gutenprint applications.

   13) Updating CUPS PPD files is now faster.

Log message:
Convert @exec/@unexec to @pkgdir or drop it.

Log message:
Remove @dirrm entries from PLISTs

Log message:
Add PREV_PKGPATH and/or SUPERSEDES for various packages that
were moved or renamed.

This was for some from 2008 and 2009 and one from 2001.

Also I noticed that a CHANGES entry was wrong as said "Renamed"
when should have said "Moved" (lua-OSBF) because PKGBASE stayed the
same.

Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Update to 5.2.3, from Bernd Ernesti.

* Changes from 5.2.2

   1) CUPS PPD files in non-English locales are now generated
      correctly when the CUPS driver interface is used (with CUPS 1.2
      and above).

   2) Epson inkjet printers that support duplex printing now use less
      restrictive margins (allowing use of more of the page) when
      duplex printing is not used.

   3) Printing to the following Epson printers has been corrected:

      EPSON Artisan 700
      EPSON Artisan 800
      EPSON BX300F
      EPSON EP-801A
      EPSON EP-901A
      EPSON EP-901F
      EPSON ME 300
      EPSON ME Office 360
      EPSON PX-401A
      EPSON Stylus NX100
      EPSON Stylus NX105
      EPSON Stylus Photo PX700FW
      EPSON Stylus Photo PX800FW
      EPSON Stylus Photo TX700W
      EPSON Stylus Photo TX800W
      EPSON Stylus S20
      EPSON Stylus SX100
      EPSON Stylus SX105
      EPSON Stylus T20
      EPSON Stylus TX100
      EPSON Stylus TX101
      EPSON Stylus TX102
      EPSON Stylus TX103
      EPSON Stylus TX105
      EPSON Stylus TX106
      EPSON Stylus TX109
      EPSON TX300F

      These printers should all be fully functional, but may be
      further tuned in the future.

   4) Duplex printing has been enabled on the Epson Stylus RX680,
      RX685, RX690, PM-A940, and PM-T960.  Support for these printers
      is still considered experimental.

   5) Support has been added for the Canon MULTIPASS MP220.

   6) Preliminary support has been added for the Canon PIXMA iP4600.

Removed the unnecessary part of the patch, about which pkglint was
complaining.

Don't use -O6 and -O3 because some gcc versions choke.
