- alsa-lib: provide dummy definitions of RTLD_* if necessary
- 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.
