Such things shouldn't be compile time optional. I don't think there's
any reason why it can't be done for every arm32 platform.

Normally I'd ask for a command line option which can overrides (i.e.
disable) this behaviour -- just in case. But I suspect that the relevant
code runs too early?

(I'll read the rest of this thread as I catch up with my email backlog).
