s390/vdso: Drop '-shared' from KBUILD_CFLAGS_64
[ Upstream commit
fd8589dce8107e2ce62e92f76089654462dd67b4 ]
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:
