nixpkgs/pkgs/development/libraries/gmp/ignore-bad-cpuid.patch
Eelco Dolstra 29b0341589 * GMP updated to 5.0.4.
* 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).

Don't abort when seeing the default CPU model/platform returned by
QEMU.
