commit d6fc24083a6075d918e6c5b0f543e9d76fe38ce6

    When writing out the runtime features to internals.h, only include the
    features in the target backend.  This prevents runtime features (like
    :executable or :heap-overflow-check) from leaking from the compiling
    system to the target system which might not have these.
