conditions:
1.Had added one line in Makefile of alsa-tools directory:
	a@a-desktop:~/NMS/kernel/2009WW21_build/src/preview-kit/alsa-tools$ vim Makefile
    LDFLAGS=-static
	
2.Had modified Makefile of directory:
	a@a-desktop:~/NMS/kernel/2009WW21_build/src/preview-kit/alsa-lib$ vim Makefile 
	./configure --prefix=$(PXA_HOST_DIR) --enable-static=yes 
	
3.after make alsa-lib, generated libasound.a
	a@a-desktop:~/NMS/kernel/2009WW21_build/src/preview-kit/alsa-lib$ make
	a@a-desktop:~/NMS/kernel/2009WW21_build/rel/host/lib$ ls
	libasound.a  and so on.
	
	
	
	Best regards!
