Comment (by birdie):
Are you absolutely sure about that?
Because when I see:
{{{
make -j4
...
STRIP libswresample/x86/audio_convert.o
GEN libavdevice/libavdevice.ver
GEN libavfilter/libavfilter.ver
GEN libswscale/libswscale.ver
GEN libavutil/libavutil.ver
GEN libpostproc/libpostproc.ver
GEN libavformat/libavformat.ver
GEN libswresample/libswresample.ver
LD libavutil/libavutil.so.56
LD libswscale/libswscale.so.5
LD libpostproc/libpostproc.so.55
LD libswresample/libswresample.so.3
STRIP libavcodec/x86/vp9itxfm.o
GEN libavcodec/libavcodec.ver
LD libavcodec/libavcodec.so.58
LD libavdevice/libavdevice.so.58
LD ffmpeg_g
LD ffplay_g
LD ffprobe_g
}}}
All the libraries are linked sequentially, i.e. just one CPU core is
active.
