checking for snd_tplg_new in -latopology... no
configure: error: No linkable libatopology was found.

+Subject: [PATCH] src/topology/parser.c: drop duplicate safe_strtol_base
+
+The safe_strtol_base() function is defined twice since
+	f547b2e3 ("conf: introduce safe_strtol_base()") and
+	5fab157a ("topology: do not call strtol directly")
+resulting in the following build failure when alsa-utils is built
+statically because safe_strtol_base is defined twice.

+Subject: [PATCH] conf: fix the export of safe_strto* functions from libasound
+
+Only one library should define the safe_strto function. Export it
+correctly and add _snd_ prefix to avoid possible clashes with the other
+application code.
