Hello
Please review this change for JDK-8250876
This changeset adds support for macos/aarch64 into build system.
macOS/Aarch64 is not yet an accepted platform for the OpenJDK. Adding
such a platform requires a JEP as is being done for the Windows/Aarch64
port.
Thanks,
David

It will allow to crosscompile for macos/aarch64 using intel mac as well.
This changeset does NOT address some arm specific issues in the macos related
code, we plan to do that in s separate commit.
An example of configure to cross-compile for macos/arm64:
--with-boot-jdk=/path/to/java/ --with-build-jdk=/path/to/same/java/as/compiled
--disable-warnings-as-errors --with-jvm-variants=zero
--openjdk-target=aarch64-apple-darwin --with-extra-cflags='-arch arm64'
--with-extra-ldflags='-arch arm64 -F/Path/To/Folder/Containing/JNF_framework/'
—with-extra-cxxflags='-arch arm64’
JNF.framework is missing arm64 part as of next macos release, but Apple has
opensourced it.
Fix to adlc were needed due to it using symbols from stdc++ and not linking to
it, so it fails when doing make images.

Thanks, Vladimir.
