kbuild: Fix 'no symbols' warning when CONFIG_TRIM_UNUSD_KSYMS=y
When CONFIG_TRIM_UNUSED_KSYMS is enabled, I see some warnings like this: nm: arch/x86/entry/vdso/vdso32/note.o: no symbols $NM (both GNU nm and llvm-nm) warns when no symbol is found in the object. Suppress the stderr. Fangrui Song mentioned binutils>=2.37 `nm -q` can be used to suppress "no symbols" [1], and llvm-nm>=13.0.0 supports -q as well. We cannot use it for now, but note it as a TODO.
