[ Upstream commit 815c1560bf8fd522b8d93a1d727868b910c1cc24 ]
With Java 11 there is no seperate JRE anymore.
Details:
https://coderanch.com/t/701603/java/JRE-JDK
Therefore the detection of the JRE needs to be adapted.
This change works for s390 and x86. I have not tested other platforms.
Committer testing:
Continues to work with the OpenJDK 8:
$ rm -f ~acme/lib64/libperf-jvmti.so
$ rpm -qa | grep jdk-devel
java-1.8.0-openjdk-devel-1.8.0.222.b10-0.fc30.x86_64
$ git log --oneline -1

$ rm -rf /tmp/build/perf ; mkdir -p /tmp/build/perf ; make -C tools/perf O=/tmp/build/perf install > /dev/null 2>1
