From: Jovan Zelincevic <jovan.zelincevic at imgtec.com>
Build system modified
There are several warnings occurring during build after this patch is
applied. The cause of most of these warnings is in that some definitions
needed here are logical part of sbr module and are added in later patches.
When this patches are applied these warnings stop occurring.
The only warning that is added here and is not fixed with later patches
is warning that warns that type mismatch for table ff_aac_eld_window_480.
The reason for this warning is in that ER AAC ELD 480 is not integrated in
to the fixed point implementation at this moment and there is no fixed point
version of this table.
