Log message:
Recursive revision bump / recommended bump for gettext ABI change.

Log message:
For packages using libao, add a default dependency on a plugin (either
oss or sun), based on the current OS name.  This is only used if no
other libao plugin is installed, and is binary package friendly.

Addresses PR pkg/30920 by Chuck Cranor.

Log message:
Remove the abuse of buildlink that was pkg-config/buildlink3.mk.  That
file's sole purpose was to provide a dependency on pkg-config and set
some environment variables.  Instead, turn pkg-config into a "tool"
in the tools framework, where the pkg-config wrapper automatically
adds PKG_CONFIG_LIBDIR to the environment before invoking the real
pkg-config.

For all package Makefiles that included pkg-config/buildlink3.mk, remove
that inclusion and replace it with USE_TOOLS+=pkg-config.

Log message:
Change path from devel/pkgconfig to devel/pkg-config.
No PKGREVISION bump since pkg-config is only a BUILD_DEPENDS.

Log message:
Fix the previous PKGREVISION bump by setting PKGREVISION in Makefile,
instead of Makefile.common.

Log message:
Replace patches that remove -ldl with those that use BUILDLINK_LDADD.dl.

Bump PKGREVISION.

Log message:
Removed trailing white-space.

Log message:
Remove USE_GNU_TOOLS and replace with the correct USE_TOOLS definitions:

	USE_GNU_TOOLS	-> USE_TOOLS
	awk		-> gawk
	m4		-> gm4
	make		-> gmake
	sed		-> gsed
	yacc		-> bison

Log message:
- Change libao to not build OSS, Sun, MacOS X nor several other plugins even
  when the header files are found.  Bump its revision to 1 due to this.
  This makes the libao package completely audio-output agnostic.
- Add a libao-macosx package containing the MacOS X plugin (sorry, untested).
- Add a libao-oss package containing the OSS plugin.  While here, use
  ossaudio.buildlink3.mk to determine the audio device instead of hardcoding
  it in a patch.
- Add a libao-macosx package containing the Sun audio plugin (sorry, untested).

Change approved by silence on tech-pkg@ for quite a long time since my
proposal.

I'm doing these changes to cleanup the base libao package.  Before these,
it contained a huge conditional to determine when the OSS and/or Sun
plugins were built, which often failed in untested platforms (PLIST
inconsistencies, for example).  Having these plugins in independent packages
makes debugging easier, keeps the dependency tree clean and also lets us use
{ONLY,NOT}_FOR_PLATFORM directives to easily say where they work or don't.
