I am 99% sure this is GMP/MPFR being miscompiled or compiled with the wrong
options and not able to run on your host.

Yes that is exactly what the macports ticket says:

So invalid.

I'm sorry, I forgot about this ticket. I can confirm that building (version
11.1) in fact works on all macOS versions at the moment

https://ports.macports.org/port/x86_64-w64-mingw32-gcc/details/

It's only broken for i686 on 10.6, but that's a completely different issue that
we need to investigate separately at some point.

(ld: illegal text-relocation to ___stdoutp in /usr/lib/libSystem.dylib from
_main in build/gengenrtl.o for architecture i386)

Is that using clang as the bootstrap compiler?

I have a patch that works around the issue with -m32 -fno-PIE producing broken
relocations with clang - but I thought Ken had already applied it?
