I don't mind this change, but so far we avoided this by simply not marking
such objects 'const'. I didn't check whether the ARM port is different in this
regard, but the x86 port till now didn't care to mark regular read-only data
read-only at runtime, so there's little point in being over-ambitious for init-
only data.
