[Buildroot] [PATCH 2 of 5 v2] alsa-lib: fix build when dynamic load is not supported (e.g. blackfin FLAT)

[Thomas De Schampheleire]

The FLAT GNU toolchain doesn't include the dlfcn.h header file.
Provide the necessary declarations (RTLD_*) to make alsa-lib happy.

[Buildroot] [PATCH 3 of 5 v2] alsa-lib: add patch to remove hardcoded -ldl

[Thomas De Schampheleire]

The AM_PATH_ALSA macro in utils/alsa.m4 unconditionally uses -ldl. This
breaks compilation of alsa-utils (and probably other packages using this
macro) for targets that do not support dynamic loading, such as for
Blackfin FLAT binaries.

This patch updates the macro to check if dlopen is available, and use that
result to conditionally add -ldl to the list of libraries.

[Buildroot] [PATCH 4 of 5 v2] alsa-utils: disable on no-mmu platforms (fork)

[Thomas De Schampheleire]

alsa-utils uses fork which is not available on targets without MMU support.
It seems to be possible to replace fork with vfork in alsa-utils, but we do
not like to carry such patches in buildroot without them being accepted
upstream.

[Buildroot] [PATCH 5 of 5 v2] alsa-utils/Config.in: move comment to top, to fix nesting of config options

[Thomas De Schampheleire]

To allow proper nesting of suboptions of a package, the suboptions should
come directly after the main option, and cannot be interleaved with a
comment.
