Now fixed hopefully

tested on Slackware 15.0 i586 no-thirdparty build  and termux/aarch64 rebuild with ffmpeg 6.0

Slackware line was:

LDFLAGS=`pkg-config --libs x11` setarch i686 ./configure --with-single-user --without-thirdparty --without-lv2 --without-libdpx

make there was:

make --version

I wonder if Debian 9 have earlier make?
