Fix hosted crossgen2 build on arm64#39537

crossgen2 (and by extension, runtime) fails to build on an arm64 box.
This is the error I see on Fedora 32 aarch64:
./build.sh
...
crossgen2 -> artifacts/bin/coreclr/Linux.arm64.Debug/crossgen2/crossgen2.dll
src/coreclr/src/tools/aot/crossgen2/crossgen2.csproj(87,5): error MSB3030: Could not copy the file "artifacts/bin/coreclr/Linux.arm64.Debug//x64/libjitinterface.so" because it was not found.
The file is there, just not under the `x64` directory:
$ find -iname libjitinterface.so
./artifacts/bin/coreclr/Linux.arm64.Debug/libjitinterface.so
./artifacts/bin/coreclr/Linux.arm64.Debug/crossgen2/libjitinterface.so
./artifacts/obj/coreclr/Linux.arm64.Debug/src/tools/aot/jitinterface/libjitinterface.so
The actual bug is that crossgen2 seems to assume that if the build is
for an `arm64` RID, it's a cross-build, not a hosted build. Fix that by
explicitly checking `BuildArchitecture` as well.
Please see dotnet/corefx#40453 and
dotnet/core-setup#8468 for related fixes
enabling building for arm64 on an arm64 machine.
I have *not* verified this change in Visual Studio.

Anyone willing to review this? The errors musl/arm64 seem entirely unrelated to my changes. |
