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.

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

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