Although I say "I guess", in fact, I already had related proofs for it. - When configure "libjava/classpath", "--disable-core-jni" is passed as parameter explicitly (can check "x86_64-.../libjava/classpatch/ config.log" to know about it). - if pass "--disable-core-jni" to "libjava/classpatch/configure", it will disable 'JNIDIR' in "libjava/classpath/native/jni/Makefile". If remove "--disable-core-jni", it enables 'JNIDIR' to build java-lang. - After grep "--disaboe-core-jni", only "libjava/configure(.ac)" do it (and hard code it). For me, the proofs are enough, and the code in "libjava/configure(.ac)" are also obvious for it. So please check it is whether it is the root cause, when you have time.
