Hmm, these default CPUs don't support vfp in thumb.

Reporter needs to try again with different configure options.  (We may still
want a more user-friendly way of catching the original problem though.)

Technically, this is ICE on invalid code, but a more user-friendly error would
be better.  As it happens, one has been added to trunk, as of 16th June.

I will backport it to 4.5, unless Mr Brook wants to.
