Title: Removed setting of NEW_RELIC_LOG in the bin/compile

The PHP Agent needs to use stderr so that it doesn't interfere with
other features and configuration on the dyno (and in fact is hard-coded
to do so in ext-newrelic.ini). So the setting of NEW_RELIC_LOG is harmless,
but not actually needed.
