Update to 2.4.2:

Changes from version 2.4.1 to version 2.4.2:
- Security fix in formatted output functions (buffer overflow).
- Formatted output functions: 6 is now the default value for
  empty precision field with %Rf.
- Better portability of configure script.
- Detection of intmax_t and uintmax_t types.
- Improved documentation: mpfr_get_z_exp, mpfr_strtofr, mpfr_get_str and
  formatted output functions.
- Improved message in case of assertion failure.
- Test coverage: 97.0% lines of code.
- Updated tcmp_ld test to really test the long double.
- Some documentation files are installed in $docdir.
- Removed mpfr_init_cache (unused and undocumented function).
- Fixed the way $CC / $CFLAGS are got from gmp.h (__GMP_CC / __GMP_CFLAGS).
- Bug fixes.
- Also note that GCC 4.4.0 (only this obsolete version) does not build
  MPFR 2.4.2 correctly; this is detected by "make check" (failures in
  tget_z and tpow_all).

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:
Change the format of BUILDLINK_ORDER to contain depth information as well,
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.

For example, "make show-buildlink3" in fonts/Xft2 displays:

	zlib
	fontconfig
	    iconv
	    zlib
	    freetype2
	    expat
	freetype2
	Xrender
	    renderproto

Log message:
Track information in a new variable BUILDLINK_ORDER that informs us
of the order in which buildlink3.mk files are (recursively) included
by a package Makefile.
