Fixes linker error http://autobuild.buildroot.net/results/c6272ac900d1a53b976839ac4f50a210b3e6b354 On powerpc64 (and powerpc64le) the build fails due to linker problems because of an old (2003) workaround for powerpc64, presumably working around an old toolchain problem that is no longer present. Removing the workaround allows the build to succeed. A new patch is added for this. Additionally, there was a mistake in patch 3: the patch added a test for HAVE_LIBDL to include/alsa-symbols.h but it was positioned in the file before config.h was included, so HAVE_LIBDL is never seen as defined. The test was also using HAVE_LIBDL (which indicates the library) rather than HAVE_DLFCN (which indicates the header).

Linking currently fails on powerpc64 and powerpc64le when configured
|
|
with --without-versioned, as follows:
|
|
../src/.libs/libasound.so: undefined reference to `.__snd_pcm_hw_params_set_format_first'
|
|
(And many similar messages.)
|
|
|
|
This appears to be due to a very old (2003) workaround for powerpc64,
|
|
(introduced by commit 06221f86) in include/alsa-symbols.h which alters
|
|
symbol names. While it was probably necessary at the time, it does not
|
|
appear to be necessary now and removing it fixes the build.
