Subject: [PATCH 65/66] perf build: Add detection of java-11-openjdk-devel package

From: Thomas Richter <tmricht@...ux.ibm.com>

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
  a51937170f33 (HEAD -> perf/core) perf build: Add detection of java-11-openjdk-devel package
  $ rm -rf /tmp/build/perf ; mkdir -p /tmp/build/perf ; make -C tools/perf O=/tmp/build/perf install > /dev/null 2>1
  $ ls -la ~acme/lib64/libperf-jvmti.so
  -rwxr-xr-x. 1 acme acme 230744 Sep 24 16:46 /home/acme/lib64/libperf-jvmti.so
  $
