+alsa-lib: conditionally enable libdl in AM_PATH_ALSA m4 macro
+
+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.
