  Sorry, I pasted the “wrong” one.  Here’s what I have for a no-asm build:
  
Ok, but these are both __gmpn_invert_limb.

  $ nm /gnu/store/924bg8ws2fkk4z0bifzkqg5d57pgc4w1-gmp-6.1.0/lib/libgmp.a|grep invert_limb
  00000000 R __gmp_binvert_limb_table
           U __gmp_binvert_limb_table
           U __gmp_binvert_limb_table
           U __gmp_binvert_limb_table
           U __gmp_binvert_limb_table
  
OK, so here we have a different defined and referenced symbol.  In what
way is that relevant for the linker error above?

  I hope this clarifies things.
  
Unfortunately, no.

This is wasting everyone's time.  Here is how:
