When clang's -Qunused-arguments is dropped from KBUILD_CPPFLAGS, it
points out that there is a linking phase flag added to CFLAGS, which
will only be used for compiling
clang-16: error: argument unused during compilation: '-shared' [-Werror,-Wunused-command-line-argument]
'-shared' is already present in ldflags-y so it can just be dropped.
Fixes: 2b2a25845d53 ("s390/vdso: Use $(LD) instead of $(CC) to link vDSO")
