I've read the first 10 lines of that chapter again, and I cannot see the
solution of the adventure game through which you want to chase me.

I'm attempting this build because a GNU package (GNU mpfr) is asking for
portability testing [1], and this package has GNU gmp as a prerequisite.
GNU package developers should "pay attention to making the program work
well with the rest of the GNU system" [2]. Therefore, please, to help
me test GNU mpfr, deal with me in a constructive manner.

The Linux/mips builds in 64-bit mode and in n32 mode succeeded (and allowed
me to test GNU mpfr in these modes); the one in 32-bit mode failed, and
I am stuck there.
