* More consequent handling of libsupc++. configure looks it up now and

provides it via BuildConfig. We link everything against it.
* Temporarily pass --no-undefined to the linker. Should be in the
  compiler specs, but isn't in the gcc 4 I built.
* Define _BEOS_R5_COMPATIBLE_ macro when building with gcc 2. Can be
  used in headers for instance.
