RFC: 8229469 JEP 386: Alpine Linux/x64 Port

[Aleksei Voitylov]

Hi,

JEP 386 is now Candidate [1] and as we resolved all outstanding issues
within the Portola project I'd like to ask for comments from HotSpot,
Core Libs (changes in libjli/java_md.c), and Build groups before moving
the JEP to Proposed to Target:

http://cr.openjdk.java.net/~avoitylov/webrev.8247589.01/

Testing:

JTReg, VM TestBase on all platforms (Linux x86_64, Linux x86, Linux Arm,
Linux AArch64, Linux PPC, Windows x86_64, Windows x86, Mac) with no
regressions. A downport of these changes to 14 passes JCK 14 on these
platforms.

The port was tested on Alpine Linux 3.8 and 3.11 with JTReg, VM
TestBase. There are no differences with Linux x86_64  with the exception
of SA which is not supported as per the JEP. A downport of these changes
to 14 passes JCK 14 on Alpine Linux.

Thanks,

-Aleksei
