[ Upstream commit 19baac378a5f4c34e61007023cfcb605cc64c76d ]
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.
