[Arm Unix build] arm variants of System.Native.a and libSystem.Globalization.Native.a are needed for cross building tests

[sergign60]

For cross building corert tests for arm architectures (see PR #2682) arm variants of System.Native.a (and libSystem.Globalization.Native.a are needed. In CoreFX System.Native.a is built from the sources. May be the same way is applicable in CoreRT also?

CoreRT gets System.Native.a and System.Globalization.Native.a via nuget package. They get build in CoreCLR/CoreFX repos and published from there.

@jkotas Could you tell which way can I get arm versions of this libraries on Linux x64 via nuget package?

[jkotas]

• System.Globalization.Native.a is in Microsoft.NETCore.Native package
• System.Native.a is in runtime.native.System package

I would expect that the arm builds for these packages may work same way as for other arm packages (e.g. dotnet/coreclr#8421).

In the meantime, you should be able to just build them in corefx/coreclr and copy them over where you need them.

(As you can tell from the inconsistent package names, there is some work to do to get this cleaned up.)

@jkotas
yes, I did as you say, built these libraries in coreclr/corefx and copied them into corert. After this the c++version of the Hello test is linked successfully.
