I've just realized what is going wrong here.  It's because the arm-linux target
is (erroneously in my opinion) including arm/unknown-elf.h.  This file defaults
the CPU target to ARM7TDMI, which means that the bx instruction becomes
available.  The patch in question just means that this latent bug has gone critical.

You can probably work around this problem for now by configuring with
--with-cpu=arm6 or some other suitable CPU.
