  build: Simplify postprocessing of linker version script files

Merged-by: Clément Bœsch <u@pkh.me>

lavc/pnm_parser: disable parsing for text based PNMs

P1, P2, and P3 are respectively the text versions of PBM, PGM and PPM
files.

We can not obtain the buffer size using av_imgage_get_buffer_size() as
every pixel in the picture will occupy a random size between 16 and 32
bits ("4 " and "231 " are such example).

Ideally, we could look for the next header (or EOF) in the bytestream,
but this commit is meant to fix a decoding regression introduced by
48ac4532d437790e56b8ed5d0d467dc88685f035.

  nvenc: fix the rc option definitions

All these commits are noop as requested by Timo Rothenpieler.

<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.

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

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.
