+From ff91d50a250e10a419bcd35176f3069161ac33bb Mon Sep 17 00:00:00 2001
+From: Sonic Zhang <sonic.zhang@analog.com>

+Subject: [PATCH] alsa-lib: provide dummy definitions of RTLD_* if necessary
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The FLAT GNU toolchain (e.g. blackfin) doesn't include the dlfcn.h header
+file, so we need to guard that include. Additionally, provide dummy
+definitions for parameters RTLD_GLOBAL / RTLD_NOW which are normally
+provided by dlfcn.h.
+
+Signed-off-by: Sonic Zhang <sonic.zhang@analog.com>
+[Thomas: don't add separate dlmisc.h, move dummy defs to global.h]
+Signed-off-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com>
+[Jörg: update for 1.1.6]
+Signed-off-by: Jörg Krause <joerg.krause@embedded.rocks>
