Change ByteArrayOutputStream's toString function to match openJDK's expectation
fix iOS OpenJDK and simulator builds

With the iOS openjdk-src build, sun.misc.Launcher will throw an
InternalError if avian.file.Handler is not present, so let's make it

Also, as of recent version(s) of Xcode, there are no utilities
(e.g. ar and strip) in iPhoneSimulator.platform/usr/bin, so we can
just use the system ones.
