[jdk11u-dev] RFR: 8257913: Add more known library locations to simplify Linux cross-compilation [v3]

[Christoph Langer]

> This backport of JDK-8257913 is another prereq for GitHub Actions in 11u. I had to make it fit a little bit. The changes to .github/workflows/submit.yml were dropped obviously as the submit.yml that I'll propose will not need the removed parts then.

Christoph Langer has updated the pull request with a new target base due to a merge or a rebase. The incremental webrev excludes the unrelated changes brought in by the merge/rebase. The pull request contains five additional commits since the last revision:
