Log message:
Allow buildling x11/libXpm with old X11_TYPE=native to replace
graphics/xpm.

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.

Log message:
Switch master site to MASTER_SITE_XORG.

Log message:
+ Don't allow the configure script to find libintl.so or else the resulting
  libXpm will be linked against it, which is not necessary.  Instead, just
  pass down INTLLIBS in the build environment for use by the [cs]xpm
  Makefiles, which are the only programs that use gettext().

Bump the PKGREVISION to 1.

Log message:
+ BROKEN_GETTEXT_DETECTION, needed on Solaris.

Log message:
Also depend on xgettext. Fixes PR 37798.

Log message:
Prepare for localisation by including gettext dependency.
