Subject: [PATCH] Disable Thumb code generation in codecs for ARM profile 65

It seems that there are a couple of codecs that use assembly optimizations. Some of their instruction sequences are not valid Thumb code. To be able to compile them successfully on TI OMAP4430, ARM mode is forced on the codecs.
