I deferred a number of changes in order to get the first set of sources
out to the mobile/dev repos.
Just so we don't lose sight of those changes, I've filed a few bugs that
can be addressed independently
going forward.
JDK-8145802: CPPFLAGS sysroot support
JDK-8145804: ARFLAGS versus AR_OUT_OPTION conflicts in static builds
JDK-8145806: OPENJDK_TARGET_CPU_LEGACY_LIB build variable will be retired
JDK-8145807: JavaLauncher should use standard naming and build constructs
JDK-8145809: Demo projects for HelloWorld for ios and android
JDK-8145811: Fix compiler warnings
