avcodec/ppc: fix broken build when compiling libavcodec with LLVM on PPC backend

Browse Source 
This commit fixes a broken build when compiling libavcodec with LLVM
compiler. These assembly files use non-standard format that is only
supported by GCC compiler. It would be nice to use a common standard
format. With this patch, both GCC and LLVM can build and generate the
same objects.
