* By default, QEMU's CPUID identifies the CPU as GenuineIntel, family 6, model 2. Since there never was a physical 64-bit CPU like that, 64-bit GMP calls abort(). This causes every program linked against libgmp to fail under QEMU (unless an appropriate -cpu or -M flag is used), which is rather bad, especially for users of hosting providers who cannot change QEMU's flags. The patch causes GMP to be more liberal (i.e., use non-CPU-specific implementations). svn path=/nixpkgs/branches/stdenv-updates/; revision=33531
