  I tried with gmp-6.1.0: the smallest value for which "make check" does pass is
  MUL_TOOM22_THRESHOLD=6.
  
I wouldn't trust setting the values outside of what we do in
mpn/minithres/gmp-mparam.h.  There MUL_TOOM22_THRESHOLD is 8.

The smallest value for equal size operands and for differently sized
operands might not be the same.
