The autoconf philosophy is that you don't test for version numbers,
you test for features.
What if this optimization is found to be broken, and disabled in a
future version of binutils? Should GCC continue to attempt to use it?
Having additional code fragments in configure.in is no big deal.
They're no maintenance burden: we don't even look at them very often.
