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.

[Thomas: don't add separate dlmisc.h, move dummy defs to global.h]

[Jörg: update for 1.1.6]
