score: Fix legacy RTEMS_STATIC_ASSERT()
In standard C pointer operands are not allowed in integer constant
expressions. Avoid a static assertion based on an array typedef since
this could lead to warnings ("variably modified 'x' at file scope" and
"typedef 'x' locally defined but not used");
This implementation requires unique messages.
