Hello Please review this change for JDK-8250876
This changeset adds support for macos/aarch64 into build system. 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.
