devel: align variable assignments

pkglint -Wall -F --only aligned --only indent -r

No manual corrections.

Log message:
Remove SVR4_PKGNAME, per discussion on tech-pkg.

Log message:
Update to libtool-2.4.2:
- Initial support for Go.
- On Mac OS X, try to open .dylib as well as .so in lt_dlopenext.
- sysroot support
- man pages for libtool and libtoolize
- various smaller bug fixes

pkgsrc side: remove support for pre-ELF NetBSD

Log message:
Update to libtool-2.2.6b. This switches libtool to the new main branch.
Changes are many, important for pkgsrc:
- much higher speed (up to 30% faster for the overall build of libX11)
- less magic for detection of the tag

The pkgsrc integration of f2c has been changed to be more sane.
libtool itself now depends on the f2c frontend to use proper
auto-configuration and only fakes up the library. This part is
encapsulated in mk/compiler/f2c.mk.

Log message:
Fix a potential security issue in libltdl by making sure that the
current directory is not included in the search path. Bump revision
of libltdl. Patch backported from tez@

Log message:
cleanup: replaced _PKG_SILENT and _PKG_DEBUG with RUN.

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:
Replace mk/bsd.prefs.mk includes with bsd.fast.prefs.mk includes.
The redundant parsing of bsd.prefs.mk is mostly avoided now and
parse time e.g. for x11/kdebase3 gets reduced by up to 10%.

Log message:
Fixed pkglint warnings, reindented the code.

Added a comment to the generated Makefile saying who has generated it,
so I don't have to look for that again.

Log message:
The libltdl directories need a "check" target as well. Otherwise
lang/kaffe does not pass the tests, for example.
