It seems that there are multiple problems with the upstream RUNTIME_PREFIX
mechanism at this time. It doesn't canonicalize argv[0] to an absolute path,
breaking calls via the PATH, for example. In addition, it doesn't seem to
locate template_dir via the runtime prefix even when specified as relative.
Revert this for now to the previous wrapper-based mechanism, but tweaked
slightly to avoid hardcoding the sysroot path into the wrapper (based on the
bits in the rpm recipe).
