8329348: jdk11u build for Windows AArch64 fails

[swesonga]

The root cause of the build error 'No rule to make target .../windows/conf/tzmappings' when building jdk11u for Windows AArch64 is that the GENSRC_TARGETS have not been built. This happens because the buildjdk is x86 but the target jdk is aarch64. Reusing artifacts is not correct in this scenario. The fix is to ensure that the required targets are built unconditionally for Windows AArch64.

Note that the existing checks for CREATING_BUILDJDK were also found to be incorrect in https://bugs.openjdk.org/browse/JDK-8217739

Builds on macOS, Linux, and Windows across both x64/AArch64 succeeded with this fix.

lines 114-116 please check the indentation I think this has to be adjusted by one space.
I am wondering how it works/worked for other cross builds then windows cross, the problem you describe sounds like it should be seen for cross builds on other platforms too?

[MBaesken]

I do not see Windows aarch in the list of supported builds for jdk11 https://wiki.openjdk.org/display/Build/Supported+Build+Platforms
so is this really worth the effort for such an old release ?

Windows AArch64 is a supported platform for jdk11u. Microsoft backported this support in #301
We are looking into updating the supported build platforms page to reflect this.

Let me investigate cross builds on other platforms to verify the build behavior.
