On 32-bit systems with an Athlon64 cpu, GMP detects it as x86_64-pc-linux-gnu. If CFLAGS/CXXFLAGS are set, GMP will try to build 64 bit libraries. The book should recommend to unset these variables before building GMP on AMD64, or to pass ABI=32 to configure (not sure whether this works well, I'll try it later...). Futhermore, GMP authors recommend to run the test suite (make check) before installing.
