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:
Update to version 5.1.2.  Patches removed above are no longer needed,
as they appear to have been incorporated upstream.  Additionally, the
following changes apply:

December 2006: t1lib-5.1.1:
---------------------------
- DESTDIR support was missing and has been addded in install-target i
  for type1afm.
- A bug fix in Anti-Aliasing subsampling code, which could make t1lib crash
  under certain conditions.
- Small number of further fixes, in particular with respect to the build
  mechanism.

December 2007: t1lib-5.1.2:
---------------------------
- Small number of fixes reported by users. The fixes pertain to a
  vulnerability issue, memory access issues.
- More decent handling if Encoding and / or FontBBox specification are
  missing (which is invalid with respect to the specification,
  but recoverable).

Log message:
Optionalize X11 support.  Requested & tested by Fredrik Ljung.
