LoongArch: Fix build error for LTO with LLVM-18
Commit b15212824a01 ("LoongArch: Make LTO case independent in Makefile")
moves "KBUILD_LDFLAGS += -mllvm --loongarch-annotate-tablejump" out of
CONFIG_CC_HAS_ANNOTATE_TABLEJUMP, which breaks the build for LLVM-18, as
'--loongarch-annotate-tablejump' is unimplemented there:
ld.lld: error: -mllvm: ld.lld: Unknown command line argument '--loongarch-annotate-tablejump'.
Call ld-option to detect '--loongarch-annotate-tablejump' before use, so
as to fix the build error.
