Signed-off-by: Bernd Kuhls <bernd.kuhls@t-online.de>
[Thomas:
 - switch to version 9.21 now that it has been released
 - add a hash file
 - switch to Git formatted patches
 - use $(HOSTCC) instead of hardcoding "gcc", and use $(HOST_CFLAGS) and
   $(HOST_LDFLAGS) instead of hardcoding -L$(HOST_DIR)/usr/lib
   -I$(HOST_DIR)/usr/include
 - add entry to DEVELOPERS file.]
