If the ARM implementation has no benefit (i.e. is no faster than the
Thumb one but takes the same/more space) then I think we should delete
it.  Having two versions of the code just seems like an unnecessary
maintenance headache and source of bugs.

What would the configure check be testing for?  If the target arch is
set to armv6t2 (which it must be if we're using this file) then, by
definition, Thumb is available.  And the fact that we've apparently
been always building the Thumb version in the past seems like a further
indication that the use of Thumb here is not a problem.
