You might get some hints if you compare the config.log for this
(succeeding) build against the config.log for the (failing) build for which
no ABI argument was provided.

With mingw-w64 port of 32-bit gcc-13.2.0 on Windows 11 I find no need to
specify "ABI=32" when building gmp-6.3.0.

However, I did strike  the same issue as you've found when I built gmp on
Windows 7 using mingw-w64 port of 32-bit gcc-5.3.0.
That was a while ago, and I simply opted to specify the ABI, as you have
done.
I haven't tried to determine where the blame lay.

Cheers,
Rob
