That thing has been a problem for a while now. Years? No one seems
motivated to issue a patch nor a new GMP release with the configure
script fixed for a modern LLVM/Clang or GCC world.

You pretty much need to hack around it and push forwards.

I suspect that GMP will fail to build all over the place soon as most
everyone has the recent compilers as default. Good luck.
