Never omit the "make clean" command after switching enabling of libreadline.
Note that depending on libreadline-6 will cause libisoburn's license to
become "GPL version 3 or later".
If you want to explictely allow only the use of libedit, then do
./configure --prefix=/usr --disable-libreadline --enable-libedit
Other deliberate dependency reduction options of ./configure are:
--disable-libacl avoid use of ACL functions like acl_to_text()
--disable-xattr avoid use of xattr functions like listxattr() on Linux
