8247589: Implementation of Alpine Linux/x64 Port

[voitylov]

JDK-8247589 is in the main issue in the third batch of a chain of backports for Alpine support to 11u as discussed in the mailing list. For the full set of anticipated changes please refer to the jdk-updates mailing list [1].

Original changeset does not apply cleanly because of:

8244224: Implementation of JEP 381: Remove the Solaris and SPARC Ports,
8215445: Enable building for Windows in WSL
8257913: Add more known library locations to simplify Linux cross-compilation
8244592: Start supporting SOURCE_DATE_EPOCH
8244752: Enable Linux support for multiple huge page sizes -XX:LargePageSizeInBytes

Testing: JCK + JTreg on Windows, Linux, Solaris, Mac without regressions.

I'll run this patch through SAP's testing tonight. I'm going to approve it when we don't see regressions.

[voitylov]

Thanks Christoph!

Hi, we noticed a small issue in test/jdk/tools/launcher/Test7029048.java .
test/jdk/tools/launcher/Test7029048.java now has private static void printSkipMessage(String description) twice ,
this leads to the error

test/jdk/tools/launcher/Test7029048.java:215: error: method printSkipMessage(String) is already defined in class Test7029048
private static void printSkipMessage(String description) {

@MBaesken thanks for spotting this. GHA gives "E: Version '9.4.0-1ubuntu1~20.04' for 'gcc-9' was not found" which is unrelated to this change.

Yes, about to fix this with openjdk/jdk11u#36 JDK-8283778

[voitylov]

@MBaesken I'd like to play it safe and kindly ask you to rerun the SAP nightly testing, if possible.

[voitylov]

@RealCLanger I see my ask to Matthias crossed with your review. Can I assume SAP is happy with the updated version?
