Subject: [PATCH 0/2] perf build: Ubuntu LTS fixes

	Hi all,

This patch series is the result of getting "make tools/perf" working on
Ubuntu 24.04.3 LTS.

There was one remaining issue, which I could fix manually, but I don't
know a good way to auto-suggest this to the user when needed.
Initially, I was greeted with:

    Makefile.config:1161: No openjdk development package found, please install JDK package, e.g. openjdk-8-jdk, java-latest-openjdk-devel

However, installing openjdk-8-jdk (or the latest version) did not help.
Apparently tools/perf/Makefile.config sets JDIR to the first Java
environment found.  Hence if a Java environment was already installed,
but it is not a full environment (e.g. just openjdk-21-jre) and lacks
the <jvmti.h> header file, the build always fails.  Only installing the
matching full jdk version (i.e. openjdk-21-jdk in my case) can fix that.

Thanks for your comments!

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
