we use the libstdc++ (including it's headers) that comes with the
compiler.
* Apparently option "-I-" has been deprecated, which is why we now treat the
include stuff a bit differently.
* Removed avcodec from the Haiku image, since the library wouldn't build with
gcc 4, and I'm not in the mood to fix that (declaration of an array of an
incomplete type).
