<BtbN> andrey_turkin, ubitux, yeah, I like the current state of nvenc in
ffmpeg, I think most remaining differences should be merged on the libav
side of things. At least I'm not aware of anything that's missing in
ffmpeg.

Only merged the explanation paragraphs. The removal of "enable/disable"
and "[no]" would create too much inconsistency and might cause
confusion.

  lavc: revert the Makefile part of 330177b5Merged-by: Clément Bœsch <u@pkh.me>

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.
