x86/build: Use obj-y to descend into arch/x86/virt/
Commit c33621b4c5ad ("x86/virt/tdx: Wire up basic SEAMCALL functions")
introduced a new instance of core-y instead of the standardized obj-y
syntax.
X86 Makefiles descend into subdirectories of arch/x86/virt inconsistently;
into arch/x86/virt/ via core-y defined in arch/x86/Makefile, but into
arch/x86/virt/svm/ via obj-y defined in arch/x86/Kbuild.
This is problematic when you build a single object in parallel because
multiple threads attempt to build the same file.
$ make -j$(nproc) arch/x86/virt/vmx/tdx/seamcall.o
[ snip ]
AS arch/x86/virt/vmx/tdx/seamcall.o
AS arch/x86/virt/vmx/tdx/seamcall.o
fixdep: error opening file: arch/x86/virt/vmx/tdx/.seamcall.o.d: No such file or directory
make[4]: *** [scripts/Makefile.build:362: arch/x86/virt/vmx/tdx/seamcall.o] Error 2
Use the obj-y syntax, as it works correctly.
