Back in commit e90a4bf4af ("alsa-lib:
don't use versioned symbols") from 2009, symbol versioning was
disabled in alsa-lib, because it was causing problems with C
libraries (such as uClibc) that doesn't support symbol versioning. The
thread at
http://mailman.alsa-project.org/pipermail/alsa-devel/2009-February/014999.html
has some background discussion about this.
Essentially, the issue was that alsa-lib in the new version of a given
symbol calls into an old version of the same symbol. If your C library
has symbol versioning, everything works fine. But if your C library
doesn't support symbol versioning, the call from the new symbol into
the old symbol will in fact end up in the new symbol, causing an
infinite recursion.
That problem was solved back then by unconditionally disabling symbol
versioning in alsa-lib.
However, some libraries such as CEF depend on versioned symbols from
alsa-lib, and the build fails during linking with versioning disabled.
This patch conditionally disables versioned symbols when unsupported
by the toolchain, leaving them enabled otherwise. We assume only glibc
has support for symbol versioning. uClibc has no support, and musl has
some limited support, so we take the safe route of only enabling
symbol versioning for glibc.

This version bump is needed prior to the introduction of alsa-plugins
1.2.5.
As part of this bump, we drop 0002-dlmisc-the-snd_plugin_dir_set.patch
which was an upstream backport, and we introduce
0002-fix-build-with-disable-ucm.patch to fix the build of alsa-lib
when UCM support is disabled. This patch is also backported from
upstream.

Passing this option disables the lfloat and ladsp pcm plugins and certain
APIs as explained by:
https://patchwork.ozlabs.org/patch/619527/
But people might want to use these even if they use software floating point,
and the size difference is really minimal, so don't pass this option.

using BR2_PACKAGE_ALSA_LIB_PCM_PLUGINS.

-ldl includes the reference to the library that has
the symbols for loading dynamic libraries.
So there is no need for this library for static only builds.
Even though alsa-lib uses dlopen, it has functions snd_dlopen
and others which can emulate dynamic linking for the static
build of the alsa-lib library and there is no need in libdl
dlopen when static build only.
This patch fixes build failures of the shairport-sync
(and probably other packages) when static libs are used.

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.
