BUG:
https://bugs.openjdk.java.net/browse/JDK-8244853
Please review this simple fix for JDK 15 which adds the required
JNI_OnLoad_extnet function to the libextnet.a
static library when it is built.
the JDK 15 make static-libs-image target currently builds this static library
but it is not spec compliant and
causes the GraalVM native-image utility to fail generating executables due to
the lack of the OnLoad symbol.
