Since LLVM 23 (llvm/llvm-project commit 0e02ccdaf010), llvm-c/lto.h includes llvm-c/Visibility.h,

which in turn includes llvm/Config/llvm-config.h. The configure macro copies lto.h and ExternC.h out

of the LLVM include directory instead of adding that directory to the include path, so copy those two

headers alongside them. Upstream: https://github.com/tpoechtrager/cctools-port/pull/192
