s390/vdso: Create .build-id links for unstripped vdso files
Citing Andy Lutomirski from commit dda1e95cee38 ("x86/vdso: Create .build-id links for unstripped vdso files"): "With this change, doing 'make vdso_install' and telling gdb: set debug-file-directory /lib/modules/KVER/vdso will enable vdso debugging with symbols. This is useful for testing, but kernel RPM builds will probably want to manually delete these symlinks or otherwise do something sensible when they strip the vdso/*.so files."
