There's a reason for that - it's already defaulting to Thumb anyway,
as that's the compiler default for armhf. Along the same lines as
changing the optimisation level (-O0 and -O1 both work fine),
switching to ARM code by adding -marm also makes the bug go away.

Maks, would you like a trivial patch to do that?

I'm also pondering the other Thumb settings in MCONFIG - as far as I
can see, CONFIG_KLIBC_THUMB is not set at the moment even though we
*are* clearly building with Thumb. Investigating now...
