It's not symlinking to the output binary - it's creating a helper link for GDB to know how to tie in the scripts-gdb package. It doesn't require vmlinux to exist at all.

It is weird to create gdb stuff as a side-effect of vmlinux. Move it to a more relevant place. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> --- Makefile | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-)
