Until secp256k1 is used for verification there is no reason for Bitcoin Core's secp256k1 to link against gmp, even if available. Pass a flag to configure to override the bignum implementation. This fixes a crash at runtime on ppc64 reported by @gmaxwell.

Nit: --without-bignum would be slightly nicer IMO |

Edit: tested and appears to work, after autogen and reconfigure,
src/secp256k1/config.logcontains... whereas it was using gmp before.
