Subject: [PATCH] Fix GCInfo library used by ARM/ARM64 protononjit builds

Otherwise, using the normal GCInfo library, the altjits will
assert creating GC info.

Create new "cross-target" builds of the GCInfo library.


Commit migrated from https://github.com/dotnet/coreclr/commit/35bd37d89e53411ef09cd0a509e6ffaaf1ab3b8a
