No, it doesn't say that I *must* set ABI.

In it says
  "By default GMP chooses the best ABI available, but a particular ABI can be

In it says
  "By default GMP chooses the best ABI available for a given system, and this
   generally gives significantly greater speed. But an ABI can be chosen

This is good. For consistency with other GNU packages, which accept CC,
CFLAGS, CPPFLAGS, and LDFLAGS variables at configure time [1] and deduce
as much configuration details from these.

I've built gmp-6.2.0 on many platforms, and on most of them setting ABI
was not necessary, if I set CC appropriately like I do for the other GNU
