[Buildroot] [PATCH 2/3] package/alsa-lib: drop patch 0002-alsa-lib-provide-dummy-definitions-of-RTLD_-if-neces.patch

[Thomas Petazzoni]

The description of this patch was no longer correct: it no longer
provided dummy definitions of RTLD_* macros since commit
ccad7db515fa79d2331e4e949aafb32eca0b5214 ("alsa-lib: bump to version
1.1.6"). All it did is make two <dlfcn.h> inclusions optional.

However, this is no longer needed, since the alsa-lib code base
contains four inclusions of <dlfcn.h>, which are all properly handled:

 - include/local.h, the include is guarded by #ifdef HAVE_LIBDL

 - modules/mixer/simple/sbasedl.c, modules are only built if
   BUILD_MODULES is enabled, and BUILD_MODULES is only enabled if
   HAVE_LIBDL is enabled

 - src/mixer/simple_abst.c, this file is only built if BUILD_MODULES
   is enabled, which itself is only enabled if HAVE_LIBDL is enabled

 - src/pcm/pcm_meter.c, this file is only built if
   BUILD_PCM_PLUGIN_METER is enabled, and this is not enabled if
   HAVE_LIBDL is not enabled.

Conclusion: the patch can be dropped. The third patch is renumbered as
appropriate.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The FLAT GNU toolchain (e.g. blackfin) doesn't include the dlfcn.h header
-file, so we need to guard that include. Additionally, provide dummy
-definitions for parameters RTLD_GLOBAL / RTLD_NOW which are normally
-provided by dlfcn.h.
