I was trying to use zend-XMLRPC today and I was receiving data back with type i8 from the XMLRPC server. As noted here, an i8 is a 64-bit integer. I am running the XMLRPC client on a 64-bit machine, where PHP_INT_MAX is 9223372036854775807, and I feel that using BigInteger is not required in this situation.

Would it be possible to add some sort of flag or configuration option, or perhaps detect if the machine is 64-bit, and in that case disable BigInteger support and simply use PHP's native integer for XMLRPC i8 types?

Code to reproduce the issue

// See https://github.com/zendframework/zend-xmlrpc/blob/9f1bf634995d0956fb1af9f63e394787c1211594/src/AbstractValue.php#L193

Expected results

BigInteger is not required on a 64 bit machine

Actual results

Error "Big integer math support is not detected" since either gmp or bcmath module is not installed.
