 The inline documentation at {{{tools/target_dec_fuzzer.c}}} states that
 building libFuzzer is required.

 However, the instructions at [http://libfuzzer.info#versions] indicate
 that the library is now part of clang.

 I recommend updating the documentation.

 The following compile instruction worked for me:

 {{{
 clang -g -O1 -fsanitize=fuzzer  tools/target_dec_fuzzer.c -o
 target_dec_fuzzer -I. \
 -DFFMPEG_CODEC=AV_CODEC_ID_JPEG2000 -DFUZZ_FFMPEG_VIDEO  -Llibavcodec
 -Llibavdevice \
 -Llibavfilter -Llibavformat -Llibavutil -Llibpostproc -Llibswscale
 -Llibswresample -Wl,--as-needed -Wl,-z,noexecstack -Wl,--warn-common \
 -Wl,-rpath-

 }}}
