Bogus library dependencies (e.g. on SDL)

Description

Summary of the bug:
pkg-config files contain unneeded dependencies (e.g. libavcodec.pc contains -lSDL)

How to reproduce:

% grep SDL /usr/lib/pkgconfig/libav*
/usr/lib/pkgconfig/libavcodec.pc:Libs: -L${libdir} -lavcodec -ldl -lva -lXfixes -lXext -lX11 -ljack -lasound -lSDL -lpthread -lx264 -lvorbisenc -lvorbis -logg -ltheoraenc -ltheoradec -logg -lmp3lame -lfdk-aac -lfaac -lass -lm -pthread -lbz2 -lz -lrt
/usr/lib/pkgconfig/libavdevice.pc:Libs: -L${libdir} -lavdevice -ldl -lva -lXfixes -lXext -lX11 -ljack -lasound -lSDL -lpthread -lx264 -lvorbisenc -lvorbis -logg -ltheoraenc -ltheoradec -logg -lmp3lame -lfdk-aac -lfaac -lass -lm -pthread -lbz2 -lz -lrt
/usr/lib/pkgconfig/libavfilter.pc:Libs: -L${libdir} -lavfilter -ldl -lva -lXfixes -lXext -lX11 -ljack -lasound -lSDL -lpthread -lx264 -lvorbisenc -lvorbis -logg -ltheoraenc -ltheoradec -logg -lmp3lame -lfdk-aac -lfaac -lass -lm -pthread -lbz2 -lz -lrt
/usr/lib/pkgconfig/libavformat.pc:Libs: -L${libdir} -lavformat -ldl -lva -lXfixes -lXext -lX11 -ljack -lasound -lSDL -lpthread -lx264 -lvorbisenc -lvorbis -logg -ltheoraenc -ltheoradec -logg -lmp3lame -lfdk-aac -lfaac -lass -lm -pthread -lbz2 -lz -lrt
% nm -A /usr/lib/libavcodec.a  | grep SDL
%

Issue is that $extralibs is generally used in the configure script for multiple modules, despite them needing different things. It causes issues for programs linking to both libavcodec/libavformat and SDL2.
