The error messages for vPortEnterCritical and vPortExitCritical are
misleading when they're called on a multi-core target, as they seem to
imply that the call is NOT supported on a single-core target. In fact,
they are, these functions are, however, not supported on multi-core
targets, so the error message has been updated to reflect this.
