>> [JDK-8323008](https://bugs.openjdk.org/browse/JDK-8323008) reports unwanted autoconf flags being added to the command line, and solves the issue by filtering out the added flags by force. This is not optimal however, as doing so leaves the autoconf message that the flags were added still displaying during the configure process, which is confusing. Instead, setting a couple of fields to disable the autoconf internals responsible for the unwanted flag is a cleaner solution
