invert_limb_table is added to extra_functions_64, for x86_&$ hosts. I
though files on that list are optional, but maybe I misunderstood. Does
the below work, and if so, is it the right way to solve the problem?

Or would it be better to add it to the more global
gmp_mpn_functions_optional (which aren't required, right?).
I don't know which would be better.
Since this table is probably quite non-standard--its values will not
make sense for all target systems, I suppose defining it as you do above
might make most sense.
