sounds like at least one shared lib was missing from final linking
stage,like "-ldl". For me on termux another android-specific files was
missed, so I added this file to ffmpeg-specific env. variable before
configure in termux.bld and disabled cli x265 encoder (because ffmpeg need
just *.a library).

I guess you can change x265 multibit patch3 , last cmake line

+cd ../8bit
+ln -sf ../10bit/libx265.a libx265_main10.a

+ln -sf ../12bit/libx265.a libx265_main12.a
+cmake ../source -DEXTRA_LIB="x265_main10.a;x265_main12.a"
-DENABLE_SHARED=OFF -DEXTRA_LINK_FLAGS=-L. -DLINKED_10BIT=ON
-DLINKED_12BIT=ON

by adding also DENABLE_CLI=OFF like in previous entry.
