#     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.
