$ pkg-config --libs opus
-L/cygdrive/[...]/i686-w64-mingw32/lib -lopus

$ pkg-config *--static* --libs opus
-L/cygdrive/[...]/i686-w64-mingw32/lib -lopus *-lm*

That's why I would recommend:
../ffmpeg/configure *--pkg-config-flags=--static* --enable-gpl --enable-version3
--disable-podpages --enable-gnutls --enable-libx264 --enable-gmp --enable-libopus
--enable-libmp3lame --enable-libtheora --enable-libvorbis
