libpostproc with --disable-avutil fails to build

[jengelh]

INSTALL.md seems to offer a way to skip generating libavutil.so (since that's already made by ffmpeg itself, postproc's libavutil.so would clash once installed).

 - if you want to install libpostproc without libavutil use ./configure --disable-avutil

Subsequently, attempting to build like that leads to a build error:

[    7s] + ./configure --prefix=/usr --libdir=/usr/lib64 --shlibdir=/usr/lib64 --incdir=/usr/include/ffmpeg '--extra-cflags=-O2 -Wall -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=3 -fstack-protector-strong -funwind-tables -fasynchronous-unwind-tables -fstack-clash-protection -Werror=return-type -flto=auto -g' '--optflags=-O2 -Wall -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=3 -fstack-protector-strong -funwind-tables -fasynchronous-unwind-tables -fstack-clash-protection -Werror=return-type -flto=auto -g' --disable-htmlpages --enable-pic --disable-stripping --enable-shared --disable-static --enable-gpl --enable-version3 --disable-avutil

Possible workaround: ln -s /usr/lib/libavutil.so libavutil/libavutil.so (but, ffmpeg-8 produces libavutil.so.60.8 while postproc produces libavutil.so.60.1, so there could be problems afoot)
