audio/opus: bump consumers after update to 1.4

One more small cleanup, forgotten yesterday.
Reported by:	lwhsu

Remove # $FreeBSD$ from Makefiles.

Update a few GNUstep ports:

 * devel/gnustep-make: Update to 2.8.0
 * lang/gnustep-base: Update to 1.27.0
 * x11-toolkits/gnustep-back: update to 0.28.0
 * x11-toolkits/gnustep-gui: update to 0.28.0

Also bump PORTREVISION on dependent ports.

Move Objective-C ports to the v2 GNUstep ABI.

 * Bump the LLVM revision used for GNUstep to 7, the minimum to support
   the new ABI.
 * GNUstep-back does not work with lld, so mark it to use Gold (BFD LD
   doesn't seem able to link Objective-C things).
 * Turn off some annoying debug logs in GNUstep back, which generate
   several messages per second when you move the mouse.  These should
   never have been enabled in a release build anyway.
 * Downgrade Cenon to 4.0.2.  This was the last version to actually work
   with GNUstep (the later ones use XCode >= 5 .xib files, which GNUstep
   can't parse).
 * Update gorm to git head. The current release doesn't work with the
   new Objective-C ABI, but -head has the patches to fix it.
 * Update PikoPixel and add it to the gnustep-app meta-package.
 * Update the three core GNUstep packages to the latest release.
 * Update gnumail and pantomime to the latest release and fix a linking
   error with the new ABI.
 * Update GNUstep FTP to the latest version.

Fix configure options for gnustep-make

We were not setting the flag to select the GNUstep ABI, so were defaulting to
using the GCC-compatible version, which was likely to trigger a lot of subtle
bugs.  This was noticed when C++ exceptions thrown through Objective-C stack
frames caused segfaults.

Update GNUstep core libraries.

Update the default Objective-C compiler.

Fix various build failures in GNUstep ports from newer versions of the GNUstep
core libraries and from changes to GNUstep Make.

Update various ports that use GNUstep and bump the portrevision of the ones
that haven't had a new release.

Remove libxslt.so.2 and libexslt.so.8 compatibility links that were added in
r374303 to prevent massive PORTREVISION bumps.  Bump dependent ports that
have not been bumped since.

${RM} already has -f.

Convert LICENSE= "GPLxx # or later" to "GPLxx+"

Approved by:	portmgr blanket

Make all GNUstep ports install into the System domain so that the Local domain
is available for stuff built from source.

Some ports were already installing in the System domain, for these just remove
the Makefile lines explicitly specifying the install domain.

The rest are installed in the Local domain, remove any overrides, update their
pkg-plists and any explicit paths in the Makefiles and then bump port revision.

Hook into the regular ports framework:
- LIB_DEPENDS for library dependencies
- Use regular USE_LDCONFIG

Reuse USES=objc (automatic)
USE_GNUSTEP is now a macro to set the dependencies and build feature needed.

Bump PORTREVISION on more ports that depend on libgcrypt after the update
in r363436 and remove the UPDATING entry because it did not guarantee
that all ports were updated nor that they were updated in the right order.
Also remove libgcrypt.la again.
