    LTO: Pass CFLAGS to compiler for kernel module linking too.
    
    Forgot to git add it in fa8104330967fab6248da216251a4382b39b1dab.
    Linker still could link LTO'ed *.o objects, because ld is invoked by cc
    with explicitly passed -plugin option that loads the liblto_plugin.so.
    This only slightly changes how LTO is performed on kernel modules.
    
    Note: this will need to be adjusted for clang -flto compatibility
    when I will update the clangb version in git module.
