Try to modify bin/Makefile. It works for me.
vlc_LDADD = ../src/libvlc.la `$(VLC_CONFIG) -libs vlc` $(am__append_2)
change to
vlc_LDADD = ../src/libvlccore.la ../src/libvlc.la `$(VLC_CONFIG) -libs vlc` $(am__append_2)
Thanks, the *-caching options can configure the buffer size.use all the *-caching options.
