RFR: 8348536: Build fails with extra cflags -DLOG_PLEASE

[SendaoYan]

Hi all,
This is complement implement PR of [JDK-8347990](https://bugs.openjdk.org/browse/JDK-8347990), which fix make fails with extra flags '-DLOG_PLEASE'. On the other hand, I think it's better check macro `LOG_PLEASE` has been defined or not before define it.
Change has been verified locally, test-fix only, risk is low.
