Correct multilib conflict of ldns-devel
    
    Prepare to multilib fix of ldns-config. Leave only last patch active,
    others are no more required.
    
    Modify ldns-config script to not contain LDFLAGS directly from compiled
    flags. Instead use $(arch) to select correct LIBIDR. Makes that script
    same for 64 and 32 bit builds. Instead of patching ax_python_devel.m4
    use simple modification of configured output.
