Tags: 7:2.4.3-1
* Import new upstream bugfix release 2.4.3.
   - Refresh Change-symbol-versioning.patch.
   - Add new symbols to the libavdevice symbols file.
* Enable libbs2b on arm64, since it is now available.
* Disable frei0r and libx264 on x32, libsoxr and openal on sparc64
  and libopencv on m68k, sh4, sparc64 and x32, because they are not
  (yet) avialable there.
* Disable assembler optimizations on x32, as they wouldn't work there.
* Include config.log in the build-log, when compiling fails.
* Add fix-hppa-tests.patch to work around a gcc bug on hppa.
