* Build library libroot_debug.so, which is the standard libroot.so with the

debug heap implementation.
* Added libroot_debug.so to the DevelopmentMin optional package. Since it has
  the same soname as the standard libroot, it can simply be specified in
  LD_PRELOAD to run a program with that version.
